Jim and Sunstar, you both give great advice, thank you very much!
As for the software, as I stated, URC stood behind their product and sent me the link stating that Magnolia is in fact a registered retail outlet, so now I have the correct software, just was too late for when I had the unit. And I will NOT give out the link or the sw, so folks, don't ask please.
Concerning the software, I did install it to take a peek at it, and it appears to me to actually be much better, and more updated (with codes!!!) than the Pronto editor. So for me to program the MX3000 looks to be way easier than the Pronto, cause unless someone has the codes I need at RemoteCentral for the Pronto, it would take me hours to program every button from 5 different remotes, into it. And that don't even include the discrete codes that it looks like the URC one has. So I am pretty much impressed with the live update for getting up to date codes, cause it looks like Pronto's last update was sometime back in 2006. As to the Active Synch problem, I think I might have that solved. I had bought a 2 GIG flash drive for Vista's ReadyBoost, but have since replaced it with a 4 GIG Corsair flash drive. So, I could install XP on the 2 GIG flash drive just for programming the MX3000, maybe??
And as I can not stand the limited funcionality of the Harmony 1000, the Pronto is outdated and harder to get the codes needed, looks like the MX just might be back in my hands again.
I know you both suggested buying online, and can appreciate all you said about that - but the local Magnolia's have them in stock, can get it the same day, and if I attempt to program it but end up throwing in the towel, they are right there to return it w/o messing with shipping and time lost. You dont know how many times a shipment was sent to me, needing my signature - but I am at work so can't. Thus it goes round and round as I try to get UPS to keep it at their center, and me find the time to drive quite a few miles to pick it up before they close. Its been a major hassle. But I will consider your suggestions. Again, thanks!
