Before people invest too much time into this, I can tell you that the issue is your script that gives users points.
It's a terrible script that's been going around for quite some time now and it fills up with data extremely quickly, making reading the file extremely slow, causing the application to freeze.
First don't assume. Dependant on the output of the command Khaled gave, we ask the user to remove all scripts and such, and see if the problem persists
Now with that said, could you link a copy of the purposed issueitive script?
