You are preaching to the choir, before the last two updates. A whole group of us, as you remember were trying to get this worked out with e-on, that it would crash within an hour or less. We also found out that that bug (that was fixed in 4.53) could crash it in 5 minutes with a steady stream of movements. It was not related to the anti-piracy system, but to the code itself. I'm not saying that you don't have a problem or that it because it works for us, it should work for you. What I am saying is that such things may never be fixed if people don't continue to work on them. I know Iloco has been talking to e-on for awhile before I jumped in on a couple of things.

My point about the serial number was not that you had an illegal copy, but whether or not e-on checks and records the serial number in some online database or not. If this is the case, then it's possible the key is considered used by the software and is confusing the system. This would show up no matter how many times you installed and on how many computers. Have they tried issuing you a new key after giving them your old one?

BTW, I had some very strange problems with Vue 4 in Win2K SP4 that I had to go back to SP3 to use it. I don't know if VuePro did that or not because it was still doing the other bug at the time I tried the update.

Disclaimer: I don't work for e-on and I am just guessing on how they do their anti-piracy. I could be wrong on whether it does check an online database.
