Yep, that's what I'm hearing from other people too. I've contacted the developer support team about it, however all I've had back so far is an e-mail saying that the issue has been passed on to the relevant team.

For you and anyone else who's already bought it, if you send your e-mail address to mike@mikeasoft.com I'll send you a copy of the .deb myself while we wait for the store problems to be fixed.
