Key store validation failed in the PC charge client verson 5.9

The following bulletin applies to those clients who have upgraded to PCCharge v5.9.x and only applies to the computer that has PCCharge running on it.
The Issue
It has come to our attention that Microsoft has recently released a Windows Security Update KB2229593 that fixes a security vulnerability in a file that PCCharge version 5.9.2 also fixes during its upgrade process. When the computer is rebooted, both PCCharge and Windows Operating System have a conflict in the file(s) effected as they both attempt to 'fix' it at the same time.
Does this affect me?
This may effect you if the Windows Security Update KB2229593 ran within the same reboot cycle as when the PCCharge Upgrade occurred. Meaning there was no reboot of the computer between when Windows Security Update was installed and PCCharge was upgraded.
If at any time a reboot of the computer happened 'before' or 'after' the Windows Security Update was installed AND 'before' or 'after' PCCharge was upgraded, then you may be ok and this situation may not effect you.
Even though you may have installed PCCharge a while ago, if your computer has not been rebooted after PCCharge was upgrade, you may be effected. If you are effected by this, the next time you reboot the computer, PCCharge may not start or function properly.
PRECAUTIONS to take in case this does affect you

1. (VERY IMPORTANT) Locate the original Microsoft Windows Operating System CD/DVD that came with your computer.
2. Plan a time to reboot the PCCharge computer. Choose a date/time when Arts Management, VeriFone Support (Monday - Friday 8:00am - 5:00pm MST) and your local IT person is available in case you require assistance. Choose a time early in the morning or on a dark day to test this to minimize any disruption to your online ticketing or box office sales. Avoid performing this test late in the day or when support may be unavailable.
3. Turn off web sales
4. Stop processing sales in the box office
5. Complete your EOD processing and close out your existing batch in PCCharge
6. Shut down PCCharge
7. Reboot the PCCharge computer
8. Test starting up PCCharge

1. Log into the computer as Administrator
2. Goto Windows >> Start >> Run...
3. Enter CMD (to goto the command prompt line)
4. Press OK
5. Enter sfc/scannow
6. Press ENTER
   1. Windows will now run "Windows File Protection" (approximately 5 - 30+/- minutes depending on your computer) and will verify the integrity of every protected operating system file on your computer.
   2. In some situations, especially in Windows XP and Windows 2000, you may also need to insert the original Microsoft Operating System CD/DVD if required by the process.
   3. Restart your computer if sfc/scannow did repair any files.
   4. Even if you are not prompted to reboot your computer after this process, reboot the computer anyway.
   5. The integrity process is completed when the window closes.
7. Reboot the PCCharge Computer
8. Test again by starting up PCCharge and processing a credit card.
