I used the regex to only allow letters, numbers and spaces, but the problem now is that if you use something other than those, it doesn't tell you that's why you get an error, it says "that username already exists", which isn't true.

If you get a SQL-error on a username with an apostrophe, then i would quickly uninstall my modifications, as you have installed a modification that is potentially open for SQL-injections.
Default vBulletin works fine with any username.
