My computer gave me the same error tonight. I'm running Mach3 3.042.035 on a ABIT BH7 1.8GHz, 2GB Ram, ATI All in Wonder 9700 Pro 128MB, with the latest video drivers. I tried to launch lazy cam from my desktop and from Mach 3 and both ways received the Gl error.
Well, in my case, Lazy Cam won't even start.....it just returns the error. I saved the crash report and will upload it tomorrow, if it will help.
Thank you,
