What version of Reader are you using? Some newer .pdf files ure using formatting codes that older versions of Reader cannot decipher and thus fail to open. Older files will still read regardless of the version of reader. Ensure you have the most recent version of Reader and try again.

We've provided solutions for some common PDF issues below.
General Tips:

• If you are having trouble opening a PDF document, one of the first things to try is updating your Adobe Reader to the latest version. You may also need to update your browser if you are using an older browser.
• Additional support is available on the Adobe Reader Support Page (Adobe.com).
• You may also want to read Adobe's more detailed troubleshooting tips.

Problem 1: Blank Page in Browser You have selected to download a file and you receive a blank page with a "Done" message at the bottom of the browser. This may be because you do not have enough space in your temporary internet file folder to complete the download.
Solution: Internet Explorer: Tools> Internet Options> Temporary Internet Files> select Delete Files
Netscape: Edit> Preferences> Under Category on the left Advanced> Cache> click Clear Memory Cache
Problem 2: Blank Page "%PDF" You received an error message containing "% PDF" or you have received a blank page while trying to download. This is due to a problem with your web browser not opening .pdf documents correctly.
Solution: Adobe Acrobat Reader 5.0: Edit> Preferences> General> Options> Web Browser Options> make sure the Display PDF in Browser box is not checked.
Adobe Acrobat Reader 6.0 and newer: Edit > Preferences > Internet > make sure the Display PDF in Browser box is not checked.
Problem 3: "Error Locating Object Handler" You receive an error message that says "Error Locating Object Handler" while trying to download a document. This is because there is a dependency with a plug-in for Adobe Acrobat while using Internet Explorer.
Solution: Please go to the following website for detailed instructions: http://support.microsoft.com/default.aspx?scid=kb;EN-US;q262213
Problem 4: Unable to Print You have successfully downloaded the pdf, can view it on your computer screen but are unable to print. This is due to a post script error with your printer.
Solution: In any Acrobat Reader program: File > Print > check the Print As Image box > OK
Problem 5: "Adobe Reader could not open file" You received the error message "Adobe Reader could not open 'filename.pdf'" because it is either not a supported file type or because the file has been corrupted (for example, it was sent as an email attachment and wasn't correctly decoded).
Solution: Adobe Acrobat Reader 6.0: Edit> Preferences> Internet> make sure the Display PDF in Browser box is not checked.

I have seen this before, First try rebooting your computer, if Adobe Reader has an erro trying to open a document once it will cause errors on every other document you try to open until the system is rebooted. If that does not resolve the issue you will likely have to uninstall then reinstall Adobe Reader.

In Internet Explorer, when you click on a link to a pdf file,
you get the error message “Adobe Reader could not open ‘filename.fdf’ because it is either not a supported file type or because the file has been corrupted.”


This error is due to an issue with Adobe Acrobat viewing PDF files in a web browser.
Try the following:

1. Open Internet Explorer, go to Tools -> Internet Options and on the General tab to erase all temporary files, cookies and history data.
2. Under Internet Explorer -> Tools -> Internet Options, on the General tab click on Settings and make sure you select the option “Automatically” for checking for newer versions of the stored pages. Then attempt to open the PDC file again.
3. If solutions 1 and 2 do not work then uninstall Adobe Acrobat, then reinstall it again.
It seems that Acrobat 6 is more prone to this error so upgrading to Acrobat 7 may solve the problem.

All d best.

Any furthur help feel free to ask me again i will be more than happy to assist you.
