ChemDraw ChemFinder: I just installed the Trial version, and when I try to launch ChemFinder, it tells me that my codes are invalid

The Trial codes expire 2 weeks from the day you receive them, not 2 weeks from the day you install the software. If you are still within the 2 week period and you get this message, the solution is to do a Find File for cfw.ini, which should be located in your Windows or WinNT folder, and then delete it. Once you have deleted it, launch ChemFinder and put in the codes again. This problem does not occur in the purchased version. It only recently started occurring in the Trial version.
