Revert to last release

This morning I installed the latest release and now have frequent crashes.  How do I revert back to the previous version

I installed V7 and have similar problem.  The main window that shows your mailbox disappears and leaves only a window where a specific message is displayed.  Once that window is closed, you must restart the application.

Just fine until this morning…! Crashes everytime I try to ajust the font size or style !   

How do I get back to the previous version !?

Hello,
the previous versions are available on our website under the Download button.

Hello

That means to delete and reinstall.
I just want a rollback.
Is possible?

PS the new look (buttons arrangement)  is horror.

Yeah. Not good. The repliy/delete etc buttons are in a frustrating spot, as well as the new search box. Not intuitive at all.
