After upgrading to 5.0.1, I'm unable to run UI scripts and get the following message: An error occurred while trying to run the script. Furthermore, recording (the bottom red button) doesn't work either. Is it the only solution to wait for Apple to fix it? Is there a way to downgrade to 5.0?
i had the same problem, and you should look at this link:

this is what Thomas W. said, and it totally solved my problem: "It is simple, just go into "~/Library/Application Support/iPhone Simulator". There is beside the folder 7.0 an folder named 7.0.3 and maybe 7.0.3-64. Simply remove the 7.0 folder and exec following command:
ln -s 7.0.3 7.0"
Hope it fix your problem!
