- cross posting isnt going to get you an answer any faster, and it creates confusion
-clicking the "notify moderator" button also isnt going to get you an answer any faster
-everyone who helps here, including moderators, does so as volunteers. every effort is made to reply promptly, but no one can be here 24/7. Please be patient instead of reposting 3 times in a few hours.
-if you can download zip or any file, your dcc is working fine. Double check to be sure (yes i know you said you disabled ignore but it never hurts to check) you arent ignoring .tar files. Ask in a help channel for the network you are on if they require a specific command to allow certain file types and if .tar is one of them. Size could be a factor only as far as your provider is concerned. The other factor to consider is that the problem is on the senders end, not yours.
