Wp All in One Security breaks Marketpress shipping options. Any thoughts ?

I am installing wp all in one security and running into a problem with the shipping options in USPS. Since enabling this plugin when checking out the customer is selecting USPS for the shipper but the shipping options are not appearing that I have enabled. I am using only Priority Mail at this point and everything was working fine until the install of this plugin. Any thoughts from others using both of these plugins? Anyone else having an issue?
