When I Click on Register Button and Insert the Password and the Account Name, it shows a Message saying "Type Account Name Properly".
Can someone Help me Pls? 

Umh... I have some dictionaries at home I can send you, if that would help...

I don't understand much how the forum works, but I'll try to get someone who does.

Try different username that not using symbols or (space). Only a-z 0-9.
