Diagonal red line through "Save As."

Win 7 pro x64
LibreOffice 5.0.1

I get this message:

Error saving the document xxx:
Object not accessible.
The object cannot be accessed
due to insufficient user rights.

What?

On a home computer with LibreOffice 5.0.3, also Win 7 X64, I open LO to create a new Writer document, enter information, and it repeatedly crashes. Every time.

So, this is two issues (should I have created two questions?).

I want to use LO regularly, but I cannot afford time to correct stuff that ought not to be happening with a product on version 5.

I want to use LO because I thought it was mature and stable.

If these are my problems, I’ll own them. Someone let me know what I ought to do to install a stable version of LO and just get on with life and work.

Thanks so much.

Please try resetting the user profile, sometimes solves strange issues.

Usually it’s enough renaming/deleting the file “user/registrymodifications.xcu”, it affects all the options in Menu/Tools/Options, and the files “user/basic/dialog.xlc” and “scrip.xlc” are overwritten, additionally custom colors in “user/config/standard.soc” are lost.

v5 is NOT stable. Go back to v4 (archive).
