Its a very simple pop-up message as follows;
HEADING of the POP-UP is TotalMix FX
message is: "TotalMix FX has stopped working correctly. Windows will close the program and notify you if a solution is available."
and then there is a Close Program tab to click.
Please note that the TotalMix window appears for a few seconds, and then it "Grays out" and then the above message pops up. I have taken a picture of this, but don't know how to attach it, nor if its necessary to attach.
Thank You.

How do I get that information? I downloaded the update drivers and firmware off the site.
Note that after the failure, I didn't know how to get to the driver and tried reloading drivers (without any success) so I reinstalled Windows. After reinstalling Windows, I still got the same message.
I am going to try the UFX on another computer. See what happens. I just purchased this unit new one week ago.
I will keep plugging away at it.
Have you seen this happen before?
thanks

Again, How can I provide the exact version numbers of firmware and drivers that I downloaded. I used the RME site to download the Windows 7 - 64bit versions. How do I check the Fireface UFX and computer to tell you the exact versions? Can I find this information on the Fireface UFX screen?
Yesterday I tried the UFX on another computer (it was running Vista), and then back on the original computer (which I now reformatted), this is a new reasonably powerful computer.
After numerous tries at various things, I have the TotalMix starting, however, I do not have control on the totalmix window size, so I cannot see all the devices (I lose site of hardware input ADAT 12 and up) as they are behind the Software input cards, in 2 line display mode. I cannot maximize the screen in either 2 line or 3 line display mode.
When powering the Fireface UFX, I get a SW 1.12 on the power-up display. Does this help any?
I am going to try to reload some of the drivers from the RME site, see if this works any better.
