@danilotaku123 Not sure why that's in Spanish. The language must be set to Spanish somewhere.
I see the message basically says:
A profile error occurred
Your profile could not be opened correctly.
Some features may not be available. Please check that the profile exists and that you have permissions to read and write its content.
That usually means the profile at "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera Developer" is being used by an Opera process or another process or its damaged or the permissions for that folder are not set to allow your user to read and write to the folder and its contents. I would rename that "Opera Developer" folder to "Opera Developer old" and then try to start Opera.
First though, I would make a test standalone installation of Opera Developer to a folder named "Opera Developer Test" on your desktop. If that Opera won't load either, there's probably really something wrong with Windows.
Does that Opera at least load right?
