Avid is not responding

Hi,

I have a PC working on Windows 10 Education Edition (i7 6700, Nvidia GTX 970, 16Gb of RAM) and when I install Avid Media Composer (8.5.0.41065) and run it with a trial license, it is running but when I click on open project, it is stopping and after if I click somewhere on the window I have "Avid Editor is not responding".

I use a dual screen (2 x Dell U2414h).

Does someone have any clue of what the problem could be ?

Thank you very much by advance,

Lucile
