I can't seem to get past the loading screen after I select my character, it keeps saying onigiri.exe is not responding. I don't know if this is a bug or if I need to go get my computer fixed, but it's driving me mad either way.

It's not you. It's a chronically unaddressed series of bugs, most prominently the infamous Kikaigahara crash bug, though it's occurred other places. Tap other posts on these issues. It wouldn't feel so bad if CS just said we see and are fixing it but we haven't even gotten that, just highly insulting distractions like fill-in comic contests. I think the most feeling here is CS has pretty much forsaken its English users and Onigiri is really a online zombie. Move on as I did to games like Savage2 or Neverwinter which are supported by companies that actually respond. As visually appealing the graphics and story, Onigiri is not the only game in town.
