I tried reinstalling minecraft, i tried uninstalling all anti virus programs. But thats not all, when i try to connect to a direct ip server my friend has in hamachi, it gets stuck in the ¨connecting to server¨ part, i can last 2 hours there and nothing, not even an error message, i have my firewall turned off, i tried a lot of things more, and nothing, my other friends (including the server hoster) can connect regularly, but i cant, i dont know why... Please help.

Did you delete the .minecraft file? If not, do that. Then, re-install Minecraft again. Get rid of all the mods you have if it still doesn't work. If it works after that,test each mod one at a time to see which mod it was making you crash.

Sounds like you messed around with the original files of Minecraft. Just like what @golddrags said. Re-install Minecraft Delete the .minecraft folder And download Minecraft and run it. The try Vanilla Minecraft.

By the way, my friend is running a 1.5.2 server, and IT WORKS perfectly fine for me, i can connect there with that version and i can play with no problems, the problem is when i use any of the 1.7.... versions. Im just too puzzled and there seems no reason for these problems to happen, i posted this here because i got tired of looking and looking the internet without finding any solutions.

So what you are saying here is that your friend has a 1.5.2 server running and you can join him with Minecraft 1.5.2 but not with the 1.7.x versions?

Yes.

Quote from Android791350

This is normal. You can't join a 1.5.2 server with a 1.7.x client.
It needs to be te same.

Take a 1.5.2 client and then join his server.

Nonono, what i meant is, that he has a 1.5.2 server and i can play fine with the 1.5.2 client, but in his 1.7.9 server, i cant join because any of the 1.7x versions i use i have the errors i told in the first post. To clarify, he has 2 servers, the 1.5.2 one and the 1.7.9 one.

Quote from Android791350

Okay... I'm sorry that I didn't understand you correctly.

I didn't play around much with 1.7.9.
You know it is the newest version right?
If it isn't modded (server and client) then ask Mojang for support.
Otherwise take 1.7.2 instead of 1.7.9.

I just read the changelog of 1.7.9 and there isn't much changed so you better be of with a older version.

EDIT: I just read some more changelogs and 1.7.2 is the most stable 1.7.x version.

ok thanks

EDIT: and w/e my problem is, i guess its finally fixed in the upcoming 1.8, i have tried all snapshots so far and i can play them without any problems (thanks mojang!)
