i'm having problems transferring files from my system to someone else's using windows messenger. other people can transfer files to me fine. i do have a linksys router and visited ms's page and found that i need to open TCP connections to the 6891-6900 range of TCP ports. however, after i do this, it still doesn't work. i have d/led upgrades to winxp, windows messenger, so i know it's not that. any1 have any suggestions?
