ADE 4.5 bugs with authorization all over and over again

Pleqase fix your bug software ADE. About ones a week, de-install and re-install, as I can not remove my account, to add it back after licenses and authorization corrupt for some reason.

No other software causes that many issues.

Really wish you would provide a reliable software to end-user - as I assume you make your money with the DRM stuff with the vendors.

error messages:

1. unable to download:
   Error getting License. License Server Communication Problem:
   
   E_Auth_bad_device_key_or_pkcs12
   
   
2. Unabel to open "TITLE"
   License key is damaged
3. cannot remove account (CTRL shift D):
   "unable to Erase Authorization. Please try after some time."

Really - what is going on?

Not the first time, I have issues... unlikewise on iPad or eReader (Tolino) but I also would like at times read content on my laptop.

Also have Adobe Acrobat 9 Professional

Adobe Acrobat Reader DC installed.
