3.1 Pre Release 9 Job Execution

I upgraded v3.1-8 to v3.1-9.
v3.1-9 will not execute an individual job nor a script.
I get the message "Toucan has stopped working windows will search for problem"

I tried deleting v3.1-8 and installing v3.1-9 rebuilding the jobs. No luck. Same message.

I have windows 7 pro 32 bit.
