IS there a way of getting around the "You need 3000 megabites minimum to install" thingy? I find it hard to believe that a patch takes up 3000mb. If there is a way please let me know!. Thanks :D

You need 3000mg free on the drive that stores your temp files so if you have a second hard drive with that much free space then you could move your temp folder location to it.
Another thing you could try is to go to another computer and run the patch and after it has extracted the files into the temp directory burn them to DVD.
Failing those two suggestions I don’t think there are any other ways around it.
