Cannot get any name verified

[Trevize]

No matter what name I try, my character's name is always rejected. I was reading around, and it sounds like WinEQ2 might help, but I also notice that it's a trial. This is also a fairly new quad-core computer that I'm trying to run it on, so that might also be a factor. Has this issue with the constant name rejection ever come up in the past?

Thanks!
