Audio Transcode Error DVD Lab

Audio Transcode Error

Hello, I'm using DVDlab Pro 1.0 to convert svcd audio streams to 48kHz audio
streams. Dvdlab uses a tool called audio transcode. I always used this tool
untill one day (I didn't install new equipment/software or anything) windows
gave me an error: in TranscodeTest MFC Application an error has accured
etc. I thought it had to do with the probably bad source audio, but when I
tried the process with a different source svcd audio, it gave me the same
error. I also tried to re-install the program, but this didn't help. So now
I can't use this excellent piece of software. Has anyone got any helpful
ideas? I can't figure it out on my own...

Much thanks in advance,
