Sage100 2015 Advanced. One workstation keeps getting ""The Credit Card Transaction request to Sage Exchange cannot be processed"" when trying to authorize credit cards. Per 1 KB article I found, I have uninstalled and reinstalled Sage Exchange both on the server and and the workstation, restarted the server, removed AntiVirus, deleted all Sage folders and uninstalled and reinstalled Sage100, but nothing works. Sage Exchange does load and the icon is in the Task Bar but the error persists. 7 other users are NOT experiencing this problem and can authorize cards with no problem. TIA
