program locks up

I did send a bug report, but now I’m trying to solve my problem.
I have been using LibreOffice for several years with no problems.
I mainly work with calc, keeping lists.
I downloaded and installed the latest Rev. 5.
When I tried to use my calc, nothing worked correctly it was always locking up on me.
I finally uninstalled it and want back to my old Rev. 5.0.2.2 which had been working just fine.
But now this old version will not work for me.
Every time I try to copy the database, the program stops working and the program shuts down.
How can I get my database to work again, I have a lot of info to install.
After I enter some data, I try to save it and every time the program stops working and the program shuts down.
Is there a solution?
