CloneCD disabled options?

[Mik3_D]

I recently installed cloneCD and it gave me a message when i installed it that certain features will be disabled... How do I get around this?

Cause I think its the reason why I cant seem to back up Gran Turismo cd's... I can make the ISO's and burn the CD's fine... but when I try to play them in my playstation (with a mod chip), it only shows a credit screen and the "legal stuff" screen and then before the title screen loads, it goes black and the CD in the playstation makes sounds like its stoping and starting again and again...

Any help would be appreciated... I'm a newbie too btw...
