Minecraft Forums

I just started to play Minecraft again, and when I downloaded the new launcher and started it up, I am getting an error: Could not find or load main class net.minecraft.client.main.Main. I never had this problem using the old launcher. I was able to play 1.5.2 on this computer just fine. After browsing the forums for the last couple of days, I could not find anyone else that had this problem and got it fixed. I would really like to play Minecraft again.

Attemted Fixes:
Un-installed and re-installed Java.
Installed all updates for Windows minus IE updates.
Renamed previous Minecraft 1.5.2 folder to remove conflicts.
Deleted the .Minecraft folder and re-installed Minecraft.

If it helps:

I have slow internet, so it took me two times to get the entire .Minecraft folder downloaded.

Development Console:

Attempt 1: http://pastebin.com/bNPppvds

Attempt 2: http://pastebin.com/2xjmVXTY

Java:
java version "1.7.0_51"
Java™ SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot™ 64-Bit Server VM (build 24.51-b03, mixed mode)

If you could help me, I would be most gracious.

You said you have slow internet, and I'm afraid that is probably the cause, as some files are downloading, yet others are timing out.
You'll have to keep retrying until all the files are eventually downloaded.

The Development Console said that I have everything downloaded successfully.

Here is the most recent Development Console window:
