Tekkit Mod doesn't run, instead goes to vanilla Minecraft

[SuperDS64]

Launcher Version: 0.5.4.9

Operating System: Mac OSX V:10.7.2

Java Version: 64-bit

Antivirus Program: When I select Tekkit at the launcher, it just runs my vanilla Minecraft. Even loads my worlds from vanilla Minecraft. It has TMI and NEI but it doesn't have all the Tekkit items. Prior to the problem, I had the Tekkit Mod updated. No error message.

@OP: You have a really old version of the launcher. A new one will likely fix your problems.

@Briannator5: Are you just saying that, or do you also have a really old version of the launcher? If so...get a new one. If not, start your own thread. Or, you know, read the 359 others on this topic.
