Foursquare Firewall? HELP!

[lilymears]

I've been trying to get my Facebook Places to work to no avail, and when I looked it up online, I started to hear about FourSquare, and how quite a few people liked it better and that it worked more efficiently than Facebook for Blackberry. So I went to the Blackberry Marketplace and downloaded FourSquare. When the download was complete, I got a message that said "The application FourSquare has attempted to open a connection to a location inside the firewall and outside the firewall which is not allowed by your IT policy." Which ... fine, whatever. But I CANNOT get the pop-up to go away!!! It has a little "ok" button at the bottom, and when I try to click it, it's like my cursor is working in the background and goes to other things on my phone with this HUGE pop up stuck in front of it.

I've turned my phone off and back on ... three times.
I've pulled my battery twice.
When I turn my phone back on, the pop-up is still there!

Someone please HELP!
