I installed Sims 2 on my new computer, it worked fine. I don't have expansions so I had to download them on the internet. I installed Daemon Tools, but it happened nothing when I mounted a ISO file. then I noticed there was no drive letter, so I had to set one. but when I tried to do that, I got a error message "Unable to set new drive letter". I googled it and it said I should go to Device Mananger and update drivers, blah. But they're already installed. After uninstalling Daemon Tools, I inserted Sims 2 CD, it happened nothing.the CD/DVD rom drive seems dead now.. I've checked Device Manager, it's still there. Did Daemon Tools deactivate it? How do I get it to work again?
