A few times I have tried to run Onigiri I get this error pop up

After that the game loads for a little while then I get error. sever file not found. Could somebody please help? I was just using it fine a few days ago.

There is might be lost files but i suggest reinstall i think?

Hm you might be missing only one file though...It's the gcml.dll in the bin file, and possibly the gcml (2).dll too.
To check which you are missing, please refer to:
Windows Start Button > Computer > OS (C:) > Cyberstep > Onigiri_US > bin
If you're missing gcml (2).dll and/or gcml.dll, do comment :p I think I might be able to send them to you.
