Minecraft Mods

[SolarHeat]

I am not the best at anything computer, so I can here! My .jar mod files dont seem to open like they show in videos... This large black box shows up for a second and then disappears! I don't know how to fix this. Please help if you know what to do.

Please tell me, I for some reason after installing this mod ceases to work properly the game. I thought maybe my ip is banned. But this is unlikely. I even managed to use a proxy server advanced.name , but still it didn't help.
