Pease help ! I cant DCC send alto I can receive and DCC chat.

When I try to DCC send, it opens send box but does not send and other party does not receive.

Checked that my IP is same as those shown in mirc options. I hear that some ISP block some ports. If this is the case in my situation, how do I work around it.

I can send on MSN, ICQ and other stuff.

Any suggestion. I do not have a router, use black ice defender (disabled and still doesn't work) and running Win ME
