Which version of Windows - I've seen something similar happen to Easy CD Creator 4 on Win98, and the cause was a particular DLL version mismatch between MSVCRTL.DLL and MSVCIRTL.DLL - if both are 6.10.xxxx, or both are 6.0.xxxx - all is ok, and a 6.10 / 6.0 mismatch one way doesn't hurt, but the other way upsets a number of programs to varying degrees.
CDRWIN is also reliant on the ASPI layer - and a visit to the forum search should bring you plenty on that!
Just thinking.... are Pioneer drives supported by BurnatOnce without any fiddling - or was Plextor (I know it was a P).
If using CDRWin in trial mode, I'd say forget it, there's plenty more out there, and CDRWin is a bit of a relic - after the fiasco of version 4.0a, version 5 (a different program) and then dropping 4.0 and supposedly bringing those enhancements back to 3.9, it's not a program I'd go looking for.
There are other (alleged) issues too - frequently accused of misuse of open source code, and of having system damage routines which are triggered by a void (or hopefully not just wrongly entered) key. Development died for a long time, and it seems it gets only a bare minimum of drive support extension.
It WAS a program that had great loyalty at one time, and possibly the best for pregap audio (hidden track) - and it also brought us BIN/CUE.
