I could not change the USB Port because i have an internal 1GB module where the open-e software is stored on.
So with the the help of the company where we bought the storage i got a link to the ISOs and installed the latest version (4562) via CD.
Later on i tried to find the ISO myself on the website .. no chance. It is ( no longer? ) linked for download!
The install routine with recovering the old licence key did not work so i had to get back to the company where we bought the storage again to get the licence key.
Install then worked without a problem.
BUT even though i uses the licence key during installation the system now states its only the trial version. How can that be? Entering the licence key in the GUI now gives me a "invalid key nessage"
