Check the date on your computer. Control panel > Date & Time
Rename cert8.db (cert8.db.old) in the Profile Folder in case there is a problem with the files.
The file cert8.db stores your user certificates, so if you have user certificates then you may want to export them now and import them after having removed cert8.db.
See Tools > Options > Advanced > Encryption: Certificates: View Certificates
If that works then you can delete the renamed file or undo the changes if you want to revert the process.
