What I will do is replace this one with the non-JIT version for now.
As for the system acting up, it is about permissions. Bear with me since I am still learning some things to improve the script. It should be fixed shortly.
Oh... one othe thing... stay away from 2.1.2 for now. From what i can tell from the files, it seems PB changed their developer and the guy definitly need to improve it if they want anything anywhere near what 2.0.6 was...
