I'm pretty sure your antivirus software is blocking PixelCNC (which is an "unsigned executable") from accessing its own files though a peek at the complete log file would give more information. I don't think all three are responsible, and that it's only one of them that's the culprit - possibly HitmanPro which is meant to prevent ransomware from accessing and encrypting your files - by simply blocking all unsigned executables from accessing anything. You should be able to add PixelCNC to a whitelist or "allowed" list of programs.
Before you do anything go ahead and paste a logfile to http://www.pastebin.com and paste the link it generates here so I can view the log in its entirety. If PixelCNC is able to generate a config file and a log file I can't imagine it wouldn't be able to at least read its font image files but something appears to be preventing it - or preventing it from utilizing the GPU properly.
No, PixelCNC does not yet "install" itself, not until we've reached the beta phase of development. If you ever want to remove it you simply delete the PixelCNC folder and any shortcuts to the EXE you've made.
