I'm getting really sick and tired of the client. Basically, this happens occasionally. Sometimes it fixes itself, but for some reason it won't this time.

I've downloaded the client, I PLACED THE .JAR FILE IN THE LIB FOLDER. As per the instructions, like it said. It's the most updated .jar file, and I've even tried older .jar files to no avail. I get a "Exception in java class "main" java.lang.NoClassDefFoundError/com/mojang/minecraft/MinecraftApplet

Everything has been installed correctly, and the client used to work perfectly (as some of you can attest to.) But it keeps doing this, and I can't use the client.

Happens to all of us, just have to keep deleting it and downloading it whenever you use it until this gets fixed.

Unfortunately, I already tried that. I deleted the entire minecraft folder, and made a clean reinstall. Didn't work, and now I have to reinstall my mods -.-

No, just replace the minecraft.jar file.
