Hi, there maybe 2 cases: - you have the lDraw AIOI part library installed on your PC - You have installed the latest lDraw parts update on your PC
In the first case rename the c:\ldraw folder and perform a new installation of my program In the second case, remove the c:\ldraw folder and perform a new installation of the program. My application actual release is still not tested with latest lDraw part library update.
Okay, I removed the line zstud.dat from the file cachelist.txt which allows the program to load and run. It still gives a horrifying crash (requiring task manager to kill it) if I try to access any znap parts, though. (Luckily I don't use znap parts.)
I should also mention that when I looked through zstud.dat, there was no line that matched the one in the error message.
