This problem could theoretically be caused by mods, so I would recommend a completely clean installation.
Your Saves Files are in "Dokumente\Bioware\Dragon Age 2\Characters", you can back up the "Characters" folder and put it back at any time after the problem is solved.
(Cloud storage is never a sufficient backup method anyway.)
You should be able to play from the point you are at now without a problem if you install the same DLC and Mods you used as the safe was made.
New DLCs will not interfere with that at all.
If you cannot install all mods, it should still be possible to force the game to load, but that depends on the mod.
