Don't use infopanel anyway, it'll block a big part of your view with stuff you should learn by heart, not by looking at a panel ;)

It's locastan's HP Pool bar mod, disable or switch to the second option. Though you have some more errors in the log than i did, but maybe that'll get you into battles at least.

Confirmed from python.log. Locastan's HP pool bar causes some irrecoverable error at battle loading. Iow., can hear sounds from the battle but just loading screen showing. The second option HP pool (arma-something) works.
