Problem with chatting=(! Please Help me!

[musicfreak69]

Hello Peoples ! I have a problem with chatting! For some odd reason I cant write nothing when I want to send a message. I can send a message but its blank because I dont know how to write something in the message. I have tried and checked everything people were told to do with problems similar to mine. I have checked my ports(and everything is right), displayed the chat columm, waited for a pop-up message to display when I press chat with host, and checked if it says true/false by the "recieved incoming this session" and it says true. I dont know what else to do ! Can somebody help me with this problem? Oh and I almost forgot, I have the LimeWire 4.8.1 version and Windows XP. Thanks !!!
