Try to run Revu as admin then try Remove/OK. If this doesn't work and you can't get to Revu/Preferences to do a reset I'll be out of ideas.
Issac I ran it as an administrator and that stupid recover whatever thing popped up. I tried remove/ ok but revu still froze up after that pop up disappeared. I will ask Revu Support for help and hope they will help me w this issue. Thank you for your assistance. You helped me w an issue in the past. You are the rock star of BB.
Hopefully they have a solution outside of re-install, let us know if they give you a good answer.
Thank you for the kind words, glad to help!
