After ading a category to the module, and the database, module just log out him from the XOOPS. This bug was discovered in GS Downloads x.x too, after 2.0.9.2 this happend with GS. It's not depend on custom_session, nor the .htaccess custom flags for the PHP.
WMP Downloads 1.1 have to work fine, the module was the only one sollution for 2.2 series until PD-Downloads 1.2 and RM+Soft Downloads Plus 1.2.
