Thanks for your help, but that didn't work.

My sister and I don't use LimeWire at the same time. She doesn't live with me anymore, but I was always able to access it on her computer and not mine.

I changed both port numbers to 56732 (where it says "Listen on Port" and "Manual Port Forward") and I'm still not able to connect.

I just recently restored my computer and I put her version of LimeWire onto my computer. I wasn't able to get connectivity before the restore or after.

Any other suggestions?
