[vandan]

I have previously used this product successfully, bu now that I have learnt to use mor options I am having trouble.
I start a burn and it dies, the following error is displayed
AppNam: vstudio.exe
AppVer: 7.0.0.0
ModName: mcmpgdec.dll
ModVer: 1.1.1.4.0
Offset: 0005a2bc

I am gaining a lot of knowledge reading this forum, I hope someone can help.
Thanks vandan
