Premier Rush not opening

[MayaYifat]

I just got a new laptop (company machine) logged into Adobe Creative Cloud and downloaded the apps I use.

Photoshop is opening OK, but Premier Rush is not - it gets non responsive/ frozen in the opening splash screen. Seems to be on the same file - 
ImporterQuickTime.prm.

Same with Premier Pro but I worry less about that because I don't use it as much. I do use Rush and need it to run! 

It is the latest version.

Have already tried:

• Logging out and back into Adobe Creative Cloud
• Uninstalling and re-installing Premier Rush (more than once)

Please help!!

Can anyone please assist with this?

I have tried the solution outlined in this post - Solved: Premiere Rush Stuck on Load - Adobe Support Community - 11335427

and it didn't help. 

(solution 2 - Deleted the preference file, rebooted and logged back into AdboceCreative cloud).

Any insights appreciated, I really need to do s ome work in Premier Rush!

Thanks
