Select a file less than 0mb file size error.

I can’t seem to to post ANYTHING to Pownce through IE 7.0.5 something, or through the app. IE doesn’t give me any errors, it simply does nothing! :-) The app. tells me to upload something less then 0MB in size! I haven’t been able to post any files so how could I have ran out of room!? Not to mention, I’ve only had the account for 2 days! Any help is appreciated! Oh, btw: OS is XPsp2 (just in case you need that)
