Feeds not processing automatically for AutoBlog 3.5.4


I have AutoBlog setup with feeds in the Network Admin area, with the feeds creating posts in one of our subsites. When I process manually it works great, but nothing ever happens when set to Automatically update (currently set to every 30 minutes). For example, when I look at the schedule, it shows that the next time they are set to run is *yesterday*

I've spent a bit of time looking over this problem in the forums, but couldn't find any clear answers for suggestions that seemed to work (canceling out a break at line 504, setting server timeout to 6 seconds instead of 3). Any help is much appreciated.

Thank you!
