My original problem was with transferring a profile to a new computer, but I'll get back to that later. In the process of trying to fix it I seem to have created another one. When I launch my *newly installed* version of Thunderbird, I get the error message "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible." Presumably this is because I deleted the profile folder - but note, I did this BEFORE uninstalling and reinstalling TB. I assumed that a new install would create a new profile, but that doesn't seem to be the case. How can I fix this problem? Note: the reason I deleted the folder is that it was corrupted when I overwrote it with my old profile, so I can't simply "undelete" it to get a working profile back. Working in Win 8, previous profile was created in Win XP.
