The seller wrote me this morning - apparently
there were problems with the old email server and
the address was changed (logical explanation 
since I know this person also had another email
with the same problems before he/she switched
to this one)... the seller asked for my 
address so he/she can send me the refund.  =)

So hopefully all is / will be resolved!

(Thank you all for the advice, too!)
