My first impression? Inhospitable to Bit Che 1.0.
Since at the moment they use 2 different script sets, BC 2.0 shouldn't completely mess up any older installation.
I guess I assumed a non-install version meant it wouldn't drop files anywhere else.
I tried to run v1 and all my settings are gone, my passwords, my columns are a mess, etc.
It wouldn't be a bad idea to have BC2 install into a different directory and create a new settings.ini there just for itself.
Trying to get a grip on the new scripting language, but removing BC2 for now if keeping it means doing without BC1.
