hubs and users prob

How are you "searching for hubs" ? You should try Public Hubs and connect through there.
"and when i insert a direct adress of a hub it shows me that i'm connected but i can't see any users that is coneected" This happens to one sole hub or to all hubs you are connecting to ? Check the address

i searched through the poublic hubs it doesn't show any results
and the prob with the users is for all hubs when i connect to a hub it writes connected but shows no users

Is DC++ allowed to access the internet ?
Do you have a firewall ?
Are you using a proxy for http ?

i don't use proxy and yes it's allowed to access the net

If you go to the Help / About DC++ menu what can you see in the LATEST VERSION box?

it says "downloading"

and than it says an existing connection was forcibly closed by the remote host

when i go to to the Help / About DC++ menu i can see in the LATEST
VERSION box 0.669

@bassdrops it means exactly that your DC++ hasn't allowed to access the net. If you can browse the net you may need to recreate the rule for DC++ in your software firewall

i did i have norton antivirus and i allowed dc to use the net ...
but it's seems that the prob is difrrent
after i turned dc on after a few hours it connects to a hub but after a few minuts it disconnect..
and still in the about box i see the same thing:
"an existing connection was forcibly closed by the remote host"
even when the hub is connected and i see users ...

Read again my lines. You need to RECREATE the rule. It means removing the rule and then reallow DC++.
