It seems there are a lot of reasons for this error message. One not so obvious follows.
I was struggling with this for hours. After reinstalling and hitting support 3 times and not getting anywhere, i restarted and made a new character.
But then i recognized the game was running in German (possibly because my Origin client also runs in german). So i edited the BIOEngine.ini and changed Language=DE back to Language=INT and BOOM "Selected Save Game could not be...". But now the other savegames were all working (again).
HEUREKA!
Now, thats what i call a missleading error message. ;-)
