Please attach the confiugation file: ~/.pypar2/prefs.xml

It looks like it's failing while reading it.

[bnsmith001 (bnsmith001)]

Here's the file you asked for... the configuration file: ~/.pypar2/prefs.xml

The file that you asked for is 0 bytes long.

I'll try to reinstall again, and reply.

[bnsmith001 (bnsmith001)]

Apparently, reinstall doesn't remove the ~/.pypar2 directory...
I had to manually delete ~/.pypar2 before reinstall.

re-reinstalled pypar2 --

When reinstall finished, there still was no ~/.pypar2 directory.
So, I loaded pypar2 from the Laucher on a whim.
The ~/.pypar2 got created as PyPar2 FINALLY started, after a week of working on this problem.

Attached is the new ~/.pypar2/prefs.xml file which has 995 bytes (not 0 bytes).

[bnsmith001 (bnsmith001)]

As far as I can tell, this can be closed.

Please make a note in man file or project docs under "troubleshooting" that -- if ~/.pypar2/prefs.xml is 0 bytes, make some room on your drives, delete ~/.pypar2 directory with command
[ sudo rm -rf ~/.pypar2 ]
then do a reinstall
[ sudo apt-get --reinstall install pypar2 ]
After executing Pypar2, the prefs.xml file will be re-created, and you are good to go.

Thank you, thank you, thank you!
