How's that DMX song go??? "I'm about to loose my mind"....

Ok..I'm checking the other PC's on the network, and sure enough, another one on the network has the exact same issue I was experiencing initially (this particular PC is blocking ip (router) to destination ip (pc)..
Now, I go to "all applications" under "network security policy" and click on "Block all unmatching request" then click the Remove button...and it says "you need to use predefined firewall policies window to delete this item"..
well, I went into the "predefined firewall policies and removed the block application policy thinking this was it...no avail...
Note..this PC is using a bit newer version than the others on the network.
