Which files or folders contain the marketpress db??

I am having issue with markepress, it de-activated when I upgraded to wordpress 4.3 last Fri, I activated it and it locked up my website. I upgraded and ran updated – no change.

Luis answered my original question: his solution – remove marketpress and then install marketpress 3.0. But first backup your db. ( I have hundred of products listed I don’t want to lose.) So, I have auto back up setup to back up to my dropbox, and the only folders I have excluded are archive and cgi. But I am not sure, when Luis said backup your Database = which files make up the marketplace db.

I just checke auto backup, it appears to be good.
