Steam game asking for game CD after I installed a patch?

[Jdw27]

I installed 1.03 patch onto my kotor 1 game which I bought from steam 3 days ago and now its asking me to instert the first play disc? What can I do and how do I un-install a patch, i think that might solve it hopefully?

Nevermind I'm re-installing it, probably work after that.

[Q]

Steam version should be patched already.
