Howdy,
Try Cartes du Ciel(CDC) or Stellarium & Stellarium Scope and see if you get the same fault. You should choose EQASCOM 5/6 if you want to run EQMOD with your mount. Are you using ASCOM 5? I gave up on SN6 Pro 6(known issues with it, EQMOD and PHD) and have gone to Stellarium, much better. If you like SN 5, you should like Stellarium. Have you joined the EQMOD Yahoo tech group? Great advise and good forum.
Cheers and clears.
PS; have you updated to .NET3 or 3.5 if you are on XP?
