Tekkit isn't updating correctly [Fixed]

[Mobius One]

OS: Windows 7 (64 bit)

Java Version: 6 and 7 both 64 bit and JDK

Antivirus: Microsoft Security Essentials

Problem:

I had a specific problem with tekkit updating to 3.0.0 and some other modpacks (including vanilla) where the launcher would redownload the same minecraft.jar multiple times then say "update failed!" No crashes just "Update Failed!". After about a half hour messing around with the files, i finally just deleted the entire tekkit directory in the .techniclauncher AFTER moving the backups I had to a different file location. I restarted the launcher and tried to update again. It worked perfectly. I have no clue why this problem occured, but it was resolved. Just thought I'd bring this up to see if anyone had a reason for this. Backups were replaced without any problems.

Error message: "update failed!"

This doesn't seem to fix the problem for I keep getting the "update now" option I say yes and after relaunching the launcher the tekkit still says to update.
