*scratches head* Uh... could one of ya'll help this idiot (i.e. Me) here?

[NightTorch]

Situation: Got Sims Vacation, got a Lite-on LTR 32123S cd writer, also have Daemon Tools and Nero Burning 5.5.7.8.

Problem: I burned a copy of Sims Vacation (had regular 'ol standard HP cd rom, put the original disc there and burnt a copy), successfully installed the game from the copy. However, when I went to play the game (With daemon tools on of course), the Sims Vacation title appeared as normal, but then the whole thing more or less disappeared on me.

Question: Is there a way to get around this? I'm probably seriously screwing up at some point or something. If this isn't normal (if it is, just say so), then could someone here please tell me the steps I'd need to do (or redo) to make a fully-functioning copy of the game? I'd just like to play the game on a regular basis without the orignal disc (Won't have access to the disc this coming week).

Background info: I'm new at this (I've been burning CD's for a whole day now and this is my first post), I really have no clue about any of these details, as the title says, when it comes to this stuff, I really am an idiot... I'm just lucky I found this website by pure chance.
