- Do NOT click the Reset button on the Safe Mode start window
Ok. I entered safe mode, the problem is gone. But I cant use my add ons now, and I have a few important ones i need to use,
Go to your add-ons page and disable some of your add-ons. Then restart. If there is still a problem, disable more of them. Once the problem is gone, you will know what group the problem is in.
Also;

And/or, if you can relay the error message in more detail, perhaps it will track down the culprit.
If the details are hard to capture and type, you could grab a screen shot. Please delete any confidential information from the image before posting.
