nLite crashing on startup

[karatesteve]

nLite has encountered a problem and needs to close. We are sorry for the inconvenience.

EventType : clr20r3 P1 : nlite.exe P2 : 1.4.5.5 P3 : 4834202f

P4 : mscorlib P5 : 2.0.0.0 P6 : 471ebc5b P7 : 1b08 P8 : 10

P9 : system.typeloadexception

I have used nLite before ... so i know it can work ... but it will not start up this time

I have .net 2.0 installed and other programs that use it are working fine

If anyone can help me out with this problem that would be great

thanks
