Scanner will not scan

I have had my scanner for a little longer then a week and it was fine for a little while but for most of the week it has been giving me the same problem. everytime I press the book pilot, the program will open, the scanner will warm up to 100% but the scanner will not scan the immage and a error message apears on the screen saying that Utility.exe has encountered a problem and needs to close. The program wont open again unless I restart the computer. I called the main technical support(plustek)number three times, got help but the problem is still not solved. I left a message for plsutek support to call me back yesterday and they didnt. I called them to day and they said they would call back, they never did. hopfully someone here will solve my problem. Plustek told me that I had to many immage devices on the computer and that is why my scanner would not work. I disabled and completly uninstalled my brother printer(fax/printer/scanner)and my logitech camera so the only immage device on my computer was the optic book scanner. I then reinstalled the book scanner and it still did the same thing. I also tried disabling my firwall and antivirus, then tried scanning but it wouldnt work. I updated everyting from the plustek website but even that wouldnt work. please tell me what is wrong with my scanner and how to fix it.
