When the computer does some incomprehensible thing, don't you always wish it would just fix itself?
That is the only explanation I can give for what just happened.
I reinstalled opera after a number of days when it was not present. No error. It just came up like it's supposed to!
I'll take it. I don't care what happened! I'm done. It's fixed.
Thank you everyone who replied and offered your help.

@sgunhouse I have done that but my base problem is that I cannot start Opera. So if Help contains more useful information when accessed through the browser that might explain why when I look at Help in my alternate browser it does not tell me anything. I see a "home page" kind of thing.
I'm on Windows 10, up to date. I'm on a Lenovo laptop.
Recently my ISP service was interrupted due to a cut cable. Since service was restored I haven't been able to start Opera. The error says "The application was unable to be started correctly. Click OK to close the application. 0xc0000022"
One solution that was recommended was to uninstall, delete the profile file (and other files I can't remember right now) and then re-install. I tried just uninstalling without deleting the profile and reinstalling but that did not correct the error.
Can someone please give me ideas where to look for the profile file? At least give me the name of the profile file?
Please and thank you!
Melissa

Even though Help says "delete your profile data" for a problem I am having I cannot fine it! It doesn't tell me the name of the file or indicate the location or even where to start looking.
Where is my profile data file located?
