I unloaded WindowBlinds, closed and re-started SD central, and everything was exactly as it should be. Weird. Now I just have to download 500,000 programs! Thanks for the suggestions.
Bought Object Desktop this evening. I have all my info (account info and serial number) printed out in front of me. I followed the directions in the FAQ for using SD Central...went to TOOLS, RESGISTER PRODUCTS, put in my serial for Object Desktop, updated it...it said it was done successfully, then i closed all that and I still can download nothing but demos. This program is overly complicated to say the least. Please help.
