The initial release of the ProSelect version 4.1 installer for Windows, was not correctly associating .psa and .tpk file with ProSelect. This meant that ProSelect would not automatically launch and load an album file or a collection file when you double-click on it (the album or collection file).

On Dec 2, 2009 we fixed the installer problem and have now placed an updated copy on the server. So if you are experiencing the above problem, simply download the 4.1 installer (for Windows) again, re-install ProSelect and all should be fine.
