I think I may know your problem now.
Perhaps GSAK doesn't know you have found them, or does not know who you are?
When you look at the list of caches in the database, are any of the caches colored yellow in the Code column?
Or more likely, perhaps you don't have your owner ID correct in the GSAK settings?
If you go to Tools - Options and look for the section under the General tab that says "Method for matching placed (hidden) and found caches" your correct user name should be in there. Or better yet, your user ID#. User ID# is the quickest and most foolproof way for GSAK to identify you. If you're wondering, your user ID# is 310400.
