I have exactly the same problem. Any solutions?

It doesn't like the file it downloaded. Md5 hash fail. :/

Retry until it works I guess?

The reason seems to be that Mojang releases version 1.5 of Minecraft today. And that the TechnicLauncher downloads minecraft.jar and checks the checksum of that and since its a new version it fails.
