I downloaded the ultimate calculus collection.  I unarchived the programs.  I installed the suggest apps.  When I click on either the App A+plus or  the programs and hit enter, I get an err : archived message. However when I check in Mem archived - it shows they are not archived.. I have tried clearing Ram and redownloading.  I am very frustrated.  Any ideas?
