logging in

April 4 my PC died and did not get a new PC until May 21. During this downtime, I didn't use my Teamviewer app. Now when I try logging in on this new machine, of course, it is asking for login credentials. The first thing I notice is the email that shows is an email address I deleted a long time ago but was once used for Teamviewer. So I tried my current email and with three Gmail accounts, I do not remember which email was used for previous successful logins. So I tried the one I believe is the correct one, jumped thru the forgot password hoops and now it is all a mess. This brings me to some questions. Is there a specific login email and password for some online account access to Teamviewer which is separate and different from a login email and password for using the app on my PC? It has been so long since I had to enter this information I am at a total loss on how to proceed. Any help will be greatly appreciated.
