Any security concerns with that?

Yes, certificates can not be checked for beeing expired/revoked/invalided. This is a risk.

Update to a newer OS/Servicepack or live with this deactivated security feature in Opera.

I guess you might need to make sure the installer finds the old one in the usual way - to overwrite (or maybe not - if Presto adopts any settings&co from the wherever existing non-standalone; I was just struck that you might be better off with installing into another directory - in order to clean the old "crap" afterwards).

Opera was running fine until the updates. It may not be related, but the timing of this new problem makes me wonder.

Check the requirements. If it's not the case - just to rule that out.

If you rather UPGRADED your OS, note that your old downloaded Opera must've matched those, previous OS requirements – but may not do for the new system. Just saying...
