I've been using bitcomet for years without any problems. The past week it simply won't download anymore. Also doesn't connect to cometID. Dht is connected. V1.40,listen port detection failed, windows 8.1. it's not my ISP as I've tested using my old computer with the latest version & it downloads & connects to cometID. I suspected my antivirus(AVG) so uninstalled it and tried another(avast) but still no chance. I have firewall exceptions for bitcomet and tried changing the listening port but nothing I've tried has worked. any help would be appreciated
