There was issue with my acdsee 3.x which installed in XP. I had used acdsee3.x for a while, at the beginning it worked great, then later on, when I browse files with thumbnail mode, it crashed every time. It was so frustrating, so I have uninstalled and reinstalled it, but that didn’t fix the problem.
Today I had googled the issue, and found the solution.
There are two files “ImageDB.dtf” and “ImageDB.ddf” that defaulted located in C:\Documents and Settings\yourusername\Application Data\ACD Systems\ACDSee. Exit acdsee (you make need to look up with “Windows Task Manager”), and deleted or remove them from that location. Run acdsee, the system will recreate the files back to same location.
