Dragon Age Inquisition won't launch at all after patch

Try a different save than the continue button one...it may have created/fried that save at some point either during the next load or update.  So try an earlier save...and learn to NOT overwrite saves, it will save you many issues, cause overwriting is a major factor in corrupting of saves.  If you have too many saves for comfort/use, then delete the earlier ones in a play, but I would keep first two and about 10 of the last just in case.
