Hi Everyone...
The demo times are based on the system clock. If you change your system time in the middle of demo this can cause the demos on the UAD2 to count down more quickly ( time-out). As lux mentioned, if you are in a dual boot system ( or boot camp ) then the difference in system times can cause the UAD2 to count down as well. Other things like a dying battery on the mobo could cause this ( time 'hickups' because of power inconsistencies ).
On a purely theoretical situation I don't know what would happen if you were in a space craft approaching the speed of light... ( time shift causing demo 'time-outs'..???) And would using a UAD at light speed reduce latency??? ; )Anywho... all kidding aside you can contact us here at UA Customer Support and we can issue you a demo reset file to get all your demos reinstated.
