It's rather strange with Flexi.
Last week, some of the USB ports on the motherboard came loose, so the UPS control connection was on and off.
I unplugged the UPS for a while, and plugged it back in. I, then, went back to work on Flexi and mind my own business.
After cancelling import of an AI file, Flexi crashed, and I rebooted the computer. Of course Flexi was among the first programs to run when I am logged into Windows 8 Pro.
The screen suddenly popped up with an error message from Flexi saying that "[n]o valid license can be found for this application." BAM! That was like a slap to my face.
I opened License Manager, and the computer ID appeared to be different. I thought I was screwed, because then I would have to remove the license from my SAi Cloud account manually, and that could only be done ONCE, which means if the computer ID changes again, I would have to pay for another PRO license. That's scary, to say the least.
I didn't realize the anomaly had anything to do with the USB device, so I restarted the computer a few times hoping the computer ID would revert to the original. No avail.
Fortunately (and unfortunately), the UPS started acting up again. As a result, I unplugged it, and restarted the computer. Ta da! There you go. My old computer ID came back!
How ridiculous was that? I have never had to deal with this with AutoCAD, 3DS Max or Adobe Creative Suites.
