Ok Where to start? I don't know much about computers. What I do know is, I have a Toshiba Satellite A70, WinXP(SP2) 60GHard Disk (partitioned) 2GB RAM, 512MB or MHz or something? But I don't think this matters at the moment. So anyway.
I was having problems playing The Sims2 on my comp. It kept randomly crashing on me. So I fiddled with it and have managed to get myself into a nice tight squeeze.
In Device Manager, DVD/CD-ROM Drives is located my DVD Drive. A Matsihta DVD RAM UJ8205. It has an exclamation mark in yellow next to it. Its Device Status Window on its Properties Tab says, "Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41)"

What have I done.

If I put in a CD it won't run, an error message comes up saying "Please enter correct CD/DVD ROM..."
If anyone out there is willing to help me out, it would be greatly appreciated.

Hi Welcome to GZ.

Try Uninstalling the driver then restart and let windows re-install it.

In Device Manager, right click on the DVD drive and click "Uninstall"

Ok, but would I have to reload the driver again? Because I don't have it on a backup.. on a CD or anything. I don't have the driver installation CD is what I'm trying to say.

Windows "Should" load a driver itself.

I know it "should've", but it "didn't". I managed to fix it though.
I accessed the following link that did all the work for me.

I (or the program I ran from the link) deleted the UpperFilters and LowerFilters registry values that do something?!
Like I know what that all means haha.

Thank You for your time Lokinz.

The UpperFilters & LowerFilters are essentially interface drivers that can modify the data stream or intercept it after it's read from the disc.

iTunes installs a filter driver for reading discs into the iTunes music database, likewise appications like DVD43 (dvd-for-free), modify the data stream to on the fly region decoding. On a sidenote the two filters mentioned don't like each other very much. I've already had to fix one machine that stopped reading discs when it had both filters installed.
