This may seem like a PITA for some but I'm new to BB and not a power user and all I want is my friking weather to work! Can someone, anyone, provide simple step-by-step instructions of what to do to make this damn stuff work????

• I am using a 7250 and on my corporate BES. I have a good rapport with the tech guy running it so if BES changes are needed all I have to do is ask.
• I want to run BBToday 1.5 or at the very least BBWeather 0.74.
• I go to the "over the air" download section and install to my BB.
• Using BBToday as an example I go to the weather settings and disable MDS proxy.
• I then get the "Unable to open a connection" error. The fix appears to be "disable firewall". What the heck does this mean? There are lots of settings on my BB but they are all set to "allow" or "prompt". What exactly do I have to do?
• My IT guy got past that error on his device but does not know how. Now he gets the lovely "DNS" error. Again, what the heck are we looking for here?

Help, please. I just want to know if it's going to rain tomorrow before I go to the beach!
