Same here. Legit version and everything. Support sent me a key, it didn't work. The sent me a link to reinstall, but I asked if that would delete my data, they said yes. Sooooo they told me to open the software and click on help > DB location to find the files and backup. Only thing is that I can't open the software hence me contacting support in the first place lol!
If anyone else is trying to backup their data here's the path:
%AppData%/Affilorma/TrafficTravisv4/
I think all you need is the databases folder in there. Make a copy of it on your desktop, then install the new version, then paste the databases folder back over top of the new one.
