Okay, so I don't know what happened, but after something like months I re-downloaded minecraft on my PC to play with a friend. When I opened, I got stuck on done loading screen. I started it with admin, and it got past the done loading, but instead was stuck in a black screen. I deleted and re-downloaded the appdata .minecraft paste, but with no success, still got the same issue. Tryed to uninstall java and download the latest version, still nothing. Then, I used a .bat minecraft error test that someone programmed, and it told me that the error Minecraft is getting is the one on the title: "Could not find or load main class net.minecraft.client.Minecraft".
I would love to get help, and since most of you guys are always friendly and helpfull, I would love some of that help.
Sorry if I posted in a wrong way or something, first time posting here, and I'm not american/live in a country that speaks english, though I'm very confident of my english.
What OS are you using? Are you running any mods or using any second party launchers?
When you redownloaded Minecraft did you use an old launcher or download a new one off minecraft.net?
I'm using windows 7. I'm not running any mods and no second party launchers, other than some failed tries on .bat archives.
I redownloaded the new Minecraft launcher off minecraft.net.
Also, Windows 7 is 64 bit, and I've installed mods for minecraft before it was "broke"
