Are you a russian player?

Are you a russian player?

yes

what is the name and realm?

the call is:

InviteUnit( name .."-".. realm )

the error is a blizzard error.  

try it manually with the same name (for example, tinystomper on magtheridon)

InviteUnit( "tinystomper-magtheridon" )

plug in the name and realm in question and see if you get the same error
