The only way you will know is to try it. We have no idea what is compatible with XP. Sell that new jet ski you bought and buy a new PC. 
You know the scary thing is we did just buy a jet ski last summer!
Got it working on XP, just updated a few steps at a time rather than the big leap I made to begin with and now it all works! Couldn't stand the thought of giving up my old trusty XP machine.
One question, does it mean anything in schedule when the text at the bottom of the main page indicating the address of the show folder is in yellow? It all seems to work, just wondered if that is anything significant.
Thanks,
Rob
