yes this game was something of a weird one, didn't take kindly to srep at all, but went along fine if you use exe,delta,lzma route.
I thought it was just my OS giving me a headache, but when multiple things started acting up , was time for complete wipe of HD & reinstall everything over again. But this still complained loudly about using srep on it. So yes its best to choose to do so without it.
thanks for posting back the info for others, much appreciated.
