I'm unable to login

When I try to login, it gives me an error summary and says it has (1) failures.
A snippet of the error is "Couldn't download https://s3.amazonaws.com/Minecraft.Download/versions/1.6.1-mcpatcher/1.6.1-mcpatcher.jar for job 'Version & Libraries'". It also says next to 1.6.1 that I'm running with mcpatcher, but I dont even have mcpatcher installed as I've removed it. I've tried redownloading it, and it just wont let me login.
