i got a new pc and when i downloaded minecraft and i tryed to log in it said that it wasnt downloaded i then deleted and redownloaded minecraft launcher a few time but it still didnt work so my friend emailed his bin folder. when i used his bin folder it worked but it said: (
<html><body><font color="#808080"><br><br><br><br><br><br><br><center>Failed to update news<br>java.net.SocketException: Invalid argument: connect</center></font></body></html>) text with a grey background. I tryed to redownload it again i even changed the time so it was perfect, disabled my firewall and did someohe stuff to my internet. I cant even play minecraft in browser! i bought a my new pc to make minecraft vids and make a server for my friends but now i cant do any of that

I even called dell but they couldnt help me

FYI my pc is dell. I have McAfee internet scurity
Please help
P.S. I can still play Minecraft offline and if i delete my minecraft.jar folder it says its updating but it never finishes and Force Update doesnt seem to do anything
