Minecraft Forums

So I recently moved my Minecraft files from a mac to a PC, and am having a variety of issues.

Originally everything went fine, but suddenly I have been receiving this message when I try to log into my account on the MC launcher.

"Sorry, but we couldn't connect to our servers.
Please make sure that you are online and that Minecraft is not blocked.
(IOException: Invalid keystore format)"
