Unable to install FreeBoard & update Customize

Just as the title says, I am unable to install FreeBoard, and I am unable to update Customize 2.0.0RC1.2 to Customize 2.0.0RC1.3. For both FreeBoard and the Customize update, installer downloads them, but in the middle of installing/updating, it gives the message: "Error - Main script execution failed!"

Please, if anyone knows any reason why it won't work on my phone, tell me.

 

Hey, I don't really care if anyone responds to this issue anymore, because I am selling my iPhone on eBay.

If you'd like to buy my iPhone on eBay, the title is called "UNLOCKED Apple iPhone 8GB Jailbroken Any GSM SIM" with the subtitle "Original Box + $200 Accessories FREE SHIPPING WORLDWIDE" I just listed it on eBay today, so it's not up yet, but it should be on the site by tomorrow. The starting bid is $400 and it is a 3 day bidding period. Also, my user ID on eBay is the same as on this website: Justinthesaint
