Hello,
the error with the Soft-eLicenser is usually solved by running the eLicenser Control Center with right-click → Run as administrator, then perform the maintenance and close the software once completed.
If this does not help, you can remove it manually by deleting the SeLicenser.sel file from C:\ProgramData\Syncrosoft (you appear to have no licenses on the Soft-eLicenser, so it’s safe to delete).
If Cubase crashes (or just stops) loading GUI resources, I would guess you are running Windows 7: please make sure it is updated and this package is installed: https://www.microsoft.com/en-us/download/details.aspx?id=36805
As per the Cubase Pro 9.5 - you already have a license for it, it was updated to 9.5 for free via the Grace Period when you downloaded the license for 9. If you purchased the update from 9 to 9.5, the order should be cancelled and the purchase refunded.
