Difficulty only uploading

[ec74w]

Hello. I have browesd around here and was unable to find an answer that sufficiently answered my question, so if this is a repeat: sorry, I couldn't find it! I have successfully downloaded from LimeWire. I was attempting to make 2 mov files available for upload so that my friend could get them. I made sure that the extensions on the files were listed under Preferences>Sharing>Shared File Extensions and the files are in my shared folder. They show up in my library and I have refreshed the library. My IP address does not begin with the numbers associated with a NAT. Some other files in my shared folder have been downloaded by other people but the 2 files that my friend was trying to download from me do not even show up in a search. Any ideas?
