TM issue after software downgrade

[Quidam]

Hi,

Running TM on a Windows 8.1 laptop.

I'm having trouble with a Titan Mobile after going back to V8.1 from V9rc : it's not responding anymore.
I'm however able to load the Titan Mobile software, so I guess the 'license dongle' part is working.
Everything I can access in the software also seems fine.

The Mobile does not appear in USB expert console (acw service is running).
Tried driver repair and of course various dumb things like plug/unplug, reboot, reinstall... none of this solved anything.
(Note : When plugged in, the TM leds does light up in the expected 'wave' pattern, then everything goes off).

Installing V9rc does solve the issue, but I need an older version of the software from now and then.
Also, as I won't be able to test it with another computer before next week, I'm left wondering if I'll be able to use this TM with anything running V8.1 (or older)...

We suggest that you install the latest version of USB Expert on top of your version 8 installation, this will work with the new drivers and is backwards compatible with the older Titan software.

Sorry for the inconvenience.
