PayPal PDT Auto-Return error after upgrading

[jdcrain]

I upgraded s2Member from 3.0 to 3.0.1 this morning and have since been running into the dreaded Auto-Return error.

"Unable to verify POST vars. This is most likely related to an invalid PayPal® configuration. Please check: s2Member -> PayPal® Options -> PDT/Auto-Return."

Is anyone else getting this after the 3.0.1 update? I've verified that all my PayPal and s2Member setting are correct and that all PDT related options are disabled. I am also not using Sandbox Testing.

I also cannot find the previous 3.0 download so that I can try reverting back. Any ideas on where I might find this?
