Pesterchum won't open :/

[squishyKiwi]

So I closed pchum last night and tried to open it this morning and it just wouldn't open and says its an error! reinstalled it a few times too. I opened the console (i'm on a mac) and the only thing that seems to be wrong is the gestalt version? I have no idea what it is help!! ):

i also am dead terrified of losing my chum handle
