After the update to the new Battle.Net launcher my Frozen Throne stopped working (even though I installed it with legitimate keys). When I try clicking play for Warcraft III I get a screen saying: ERROR THERE WAS AN ERROR IN HANDLING THE REQUEST.
I uninstalled the game and realized I had lost my original CD-Keys for Reign of Chaos and The Frozen Throne that I purchased over 10yrs ago. Is there any way to recover these keys so I can play Frozen Throne again on Battle.Net matchmaking?
