well, i had a close look at this right now and if you are on LowID, it shoudl display "LowID" instead of "unknown". so something is broken.i now people who has had this very same problem as you and have been able to fix it just by deleting the ~/.eMule file (NOT ~/.aMule directory). Instead of deleting it, please move it elsewhere and, if it fixes your problem, send it to me, please.
Also, please tell me what exactly is showing "My info" as "IP:Port".
Thanks and greetings!
