I installed Magix Photostory Deluxe on Sunday and used it. Today (Monday) an upgrade was offered, I accepted it. Now it won't open and wants me to register (which I already did) with pre-entered email and serial number. When I enter my password, it says already registered under the same email address. Error -24
Browse your account here, select My products after logging in and check that there is an activation slot free, if the 2 slots are occupied, then deactivate the one for your computer, then try activating Photostory again.
