No idea Klaus, sorry
I used Click2Pay years ago, and then I had problems with them.
Some things they did charge double, other things they did not credit, it was a mess.
Hope this has improved by now.
However, if the account is inactive, you should maybe ask how to activate it again?
And why would you like to get money on a inactive account? Even if it would be possible to receive monies, then what would you do with it, don't you could use it as long your account is inactive?!
