New Rgistrations Are Refused

[mam14]

I am still testing a Hebrew version of vB2.0 where I had my UBB6x forum transfered to vB, and I came across a big problem by which users cannot register names in Hebrew as they are told that the name is already registered even though they aren't! I don't have the same problem with English names however.. Any thoughts?
Is there a template which needs to be edited (maybe I mistakingly altered one while translating).
Note that I don't have a character set problem as I have placed the correct CS in all the templates (in the header section thru cp)..

Remove this (and only this, exactly):

OR username='".addslashes(eregi_replace("[^A-Za-z0-9]","",$username))."'

From line 191 of register.php and see if that helps.
