after installing the v1.1 patch to GPL (mainly people with the UK
version are affected as I think other versions do not have cd
protection?).
Go to:
http://www.racesimcentral.net/
And download the nocd-gpl1103uk.zip file.
This nifty little file (Less than 1kb in size) will cure the problem,
simply d/l it, extract the com file to your GPL directory and run the
com file. You no longer need the cd to run the v1.1 patched version of
GPL.
