buffer error - portable version

[koschmu]

When trying to run this .rb in an editor-tab, i get this message:

Your code buffer has reached capacity.
Please remove some code before continuing.
For working with very large buffers use:
run_file "/path/to/buffer.rb"

I use the portable version and don't get it :-) I found some buffer.rb in different sub-directories, but they seem not to be the correct ones...

What can i do?
