The problem you are experiencing is likely a result of the fact that the program by default remembers all settings upon exit, and when it is started again, it automatically applies those saved settings. Now, if somehow these settings get corrupted for whatever reason, it may occasionally fail.

Please follow this procedure to restore the program to the working order by clearing your settings and resetting them to their default working values:

1. Download http://download.binarymark.com/ResetProg.exe and run it with Administrative Privileges (download and save it first, then right-click on the downloaded file, and select Run as Administrator).
2. In the "Reset (Clean up) Program's Settings and Options" box in the drop-down list select the program with which you are having problems (normally there will be just one, but if there are several of them with weird names, look for the one that starts with the name of the program's executable file - it should also be obvious to determine the correct item by looking at its name). If you find several items in the list that match the criteria for belonging to the program you are having problems with, then repeat this step and the next for all of the items.
3. Click on the "Clean up" button that appears right next to the program you selected in step 2. If successful, you will get a confirmation. Note: Unless instructed by the support team, do not clean up the program's data in the box at the bottom.
4. If the operation did not succeed, or you were not able to locate your program in the drop-down list, close the Settings Reset Tool and follow these steps instead:
1) Enable viewing hidden and system files and folders. Start, Control Panel, Folder Options, View, and select "Show hidden files, folders, and drives" under "Hidden Files and Folders".
2) Make sure the program is not running and delete the following folder using Windows Explorer: "C:\Users\[username]\AppData\Local\BinaryMark" (for Windows Vista/7) or "C:\Documents and Settings\[username]\Local Settings\Application Data\BinaryMark" (for Windows XP), where [username] should be substituted with you username you use to login to Windows. To do that, click Start, (my) Computer. In the window that appeared double-click on "Drive C:" in the list and navigate your way to the above folder by repeatedly double-clicking on the needed folder (every click will move you down in the folder hierarchy) until you reach "BinaryMark" folder, at which point you should right-click on it and select Delete.
5. Try starting the program again, and if certain preferences were the culprit, it should work.

This may happen if the activation information file that the program creates when you activate it, is modified, moved, or deleted. So, please make sure that neither you nor any software (such as Anti-Virus for example) modifies the contents of the following folder in any way: "C:\Users\All Users\PAI" for Windows 2008, 7, and Vista or "C:\Documents and Settings\All Users\PAI" for Windows XP and 2003.
