I thought I'd share this info for those who may be having or might go thru the same problem I did.
I was used to using KHPro with .wav files but decided to have a go with mp3 files to enable me to export the song as a MP3 + G file. I followed mtu's page to download and install the lame_dll file etc
I then converted a ".wav" file and saved it as a "lame mp3(*.mp3)" but KHPro didn't like it and it kept crashing.
So I converted the same ".wav" file again but this time, saved it as a "mp3/mp3PRO(*.mp3)" and it worked! I had no idea there was a difference?
Anyway, KHPro now works with mp3's and I can export it as "mp3 + G" files. YEAH!
I hope this might help others. Thank you again guys for your responses, I really do appreciate it
