simply re-install the game in a different folder and add things you really need one by one. I strongly believe that will solve your every silly problem.
To uninstall means by deleting everything in the appdata folder [in this case, its library as this is a mac].
Macs don't have uninstall executables. To install, its just a disk image, open the 'disk', drag the app to appfolder, click on the app.
=( There's like 50 gb worth of 'installments' in there. Apprently, meisseli, ur HUD for 1.1 fixed oticz's HUD problem.

THX!
Now there is just gpp. Apprently the only good thing ur 1.2 HUD made is that now my shotgun has a crosshair [the additional dot]. [there was a missing crosshair pack, and it says 'using default', can't find default... continue skipping error or something like that. Also, it says similar stuff on the 1.1 console before i had ur HUD installed. For example (this is a sound file error example, not what it actually says),

**This is what i saw as a glimps before trem 1.1 force-quit'ed' itself [it never quit though, the window just goes blank and i can't switch windows or anything as its fullscreen, i need this off]. It kinda loops this several times for a whole hour in the mac's OS console. This wasn't the actual file that was missing, but it is just sort of an example of what happens. Its like the folder itself is half-copyright. I kinda get this problem on my Ubuntu virtual machine, when i try to install trem 1.1 there, it says 'cannot access folder' or 'has no rights to write to this file' or something...
TLDR?: That was an example of what happens to my client.
2nd thing: When i change mods in gpp, it goes to fullscreen and NEVER exits. Console doesn't work.
But gpp is different: it doesn't EVER quit fullscreen.
