One client with BW can not do Debit Memos

SOLVED

I have a computer where I get 'Field type not supported for xml' when trying to perform a Debit Memo tran. I have already tried re-installing BW 2011 twice and also gave my windows xp acct, administrators access but to no avail. Does anybody have an idea what's wrong with this one client computer? The debit memo tran works fine on our other client computers.

Thank You.
