Build #62 Error on updating

From changelog: "Update if latest build number differs, not only if it is higher than the current one."

Starting MultiMC now asks if I want to "update" MultiMC from version 62 to version 4.

Solution: Reverse this change.

EDIT: Noticed that there's a new project on Jenkins "MultiMC 4 - Windows". Slightly confusing. Can't rename the original project name?
