"Media cache directory" issue : Premiere Rush is not openable
Premiere Rush V1.2.12 built 10.
Hi,
Trying to start working with Premiere Rush but everytime the process blocks on the same issue. When starting, the following message displays :

At first, I thought hitting "ok" would re-initialize the media cache directory enabling me to work. But, the software blocks when opening a new project or anything : it stays at "preparing the project" for hours. I tried to download the soft again, add a new directory, change version etc... Nothing worked.
Any idea on how I could set this issue ?
Should you need other informations, please ask me. Thank you for your help.
