I started having problems with ACDSee 4 PowerPack quite some time ago, especially with PicaView 2.0. Finally determined it was caused by an MS security update for XP (HTML Help security update). There might have been a recent MS security update that broke yours even further, that's if you are on XP. I scrapped ACDSee. I sure do miss PicaView... It was an excellent little piece of software from ACD Systems.
