When I called the support number, they basically told me it was something wrong with my computer if it ran OK on 32-bit and wouldn't run on my 64-bit. I'm sure it's just that the old executable won't work under the 64-bit operating system. I guess I'll try back tomorrow to see if I can get a tech support person that will send me the new exe. If any of your who got the new 64-bit exe wouldn't mind forwarding it to me, that would make my life a lot easier. If not, I understand and I'll keep trying with support. Thanks!
