Problem authorizing the .ascm files i downloaded from over drive.

My computer has been using ADE find for a while now, but today when trying to open the files from overdrive, i keep getting an error.

Theres no reason for this, as my computer has been an authorized device for a long time.

These are the steps i tried, but none has worked:

-closed and reopened the program

-restarted my PC

-uninstalled and reinstalled ADE (version 4.5.1)

-Deauthorizing the device....and hoping to reauthorize... but i got an error also, when i tried to deauthorize.

Any ideas on how to fix this?

PS, could it be overdrives fault? I downloaded the .ascm like 2 minutes before trying to load them into ADE.
