Newest Update Deleted ALL Technic Items

[itsB0D3]

Launcher Version: Rec. Build for 1.2.5

Operating System: Windows 7 Home Premium SP1 64 bit Acer Aspire

Java Version: 1.7.0_05

Antivirus Program: McAfee

Description of Problem:

Basically when I logged in after updating the launcher to the latest build, I converted my save as usual, but when I logged in, EVERYTHING that was related to technic such as ALL my machines, my quarry, pipes, even all the items in my chests were gone. I first realized it since my house was made out of marble prior to updating that there were no walls, no floor, just a roof and floating torches. WTF. So basically anything that was part of the mod pack disappeared from my world.

Error Messages:

None

Error Log:

Technic 7.2 is not backwards compatible due to the giant 4096-ID migration and a bunch of mod upgrades. Unfortunately, you are limited to backdating your launcher and restoring a world backup, or starting new.
