Cron Issues

I’ve had a website set up with Cron for several months. I thought it was all working fine. Last night I started getting permission denied e-mails concerning the cron job. I’ve been getting them all day. I opened a ticket this morning ([SIZE=11px][FONT=Tahoma]MNY-49120-247) [/FONT][/SIZE]and they responded and said that they changed permissions. I’m still getting the error.

Is there something that has changed with cron jobs? Is there something that I can do (besides deleting the cron job) to rectify the issue?
