I was switching PCs and one was "probably" not shut down properly.
When I plugged in my portable drive containing portable apps and clicking on Mozilla Thunderbird, Thunderbird wanted to create a new account as if the old one does not exist.
I can go directly to the ThunderbirdPortable/App/Thunderbird/Thurderbird.exe and get my email this way but not by bringing up the portable app and clicking on Mozilla Thunderbird. It wants to create a new account.
How do I fix this?
