I paid for TradeKeeper in March 2006. Unfortunately, my computer died, and so did that software. When I contacted the software manufacturer for a copy of the intallation file, they said that version didn't exist anymore and that I should have saved that file myself. I do have the key that they sent me (tk34key.zip), but they refuse to send me the installation file. Does anybody have an older version of TradeKeeper from the last year?
