Unable to use free acrobat

I had the free version of acrobat on my computer. My wife logged in to her Pro version on my computer, then logged out. Now I can't get into the free version (which is all I need) because it keeps saying to buy or start a free trial which I don't want to do. We have logged out, uninstalled and reinstalled the free version, rebooting the computer and clearing the casche. Any suggestions? I only need a reader for bills that come in for the non-profit I volunteer for. I do not want the paid version. Thanks.
