If you are trying to register that as the URL, then I would guess the. is the problem; instead of .wikia.com (one prefix), you are trying to make. .wikia.com (two prefixes).

Try using vileexe.wikia.com or vile-exe.wikia.com instead. The period has a special meaning in URL schemes, so can't be used in wikia names.

If you just mean the name of the wikia, I don't know if the same restriction applies.
