searching but no results....because of a firewall?

I work for a corporation and I just downloaded LimeWire. I was previously using Audiogalaxy and was having no problems downloading music. My LimeWire search page comes up, I search for music, and I get no results. Is this because I might be behind a firewall? If so, how can I circumvent it to use LimeWire?

I am having a similar problem. The first search I tried had 3 results and these were displayed without a problem. The next searches I tried showed that the search was complete and the number of results in brackets but did not list the results individually in the window. However I can scroll down as if the list were there only I can't read it -- it's as if the text is white and can't be read since it's on a white background. If you have any suggestions at all they would be really appreciated!!

The first search I tried had almost 300 results and these were displayed without a problem. I downloaded the song until 52% and it stopped and didnt do anything at all. I tried again and stopped the download and I couldn't find any results for the same song. I have another problem too,: I try to launch my songs when they are finished and they take forever to play and don't play at all. If you have any suggestions at all they would be really appreciated!!
