Bought update for wrong version

Hello Chaps. Wanted to acquire additional FTP features. On purchasing (Receipt # 362313), stupidly put in reg code for the older version (DOpus9) I have on older computers here. Tried to update on thismachine and of course the license manager pointed out my mistake. Can I cancel the previous transaction and get the FTP addition for DOpus 10 instead?. Many thanks.

Please email for assistance.

Many thanks.
