What does the yellow alert say? the ffs beta warning has a long english text. Is the alert you're getting a recoverable alert (guru)? Which number? Also, I don't recommend using stuff beyond BB2 or only very selective. I even would advise you not to use the new exec.library and ram-handler from BB2 (and later).
And never ever install anything by Cosmo on your machine. Don't do it. It will not significantly speed up anything, but rather cause incompatibilities and an unstable machine.
