NEI acting up

Title: NEI acting up

Version: 0.5.1

OS: Windows 7 Home Preuim

Java Version: Java 7.11

Description of Problem:

NEI isn't working properly. Whenever I click the noon button, instead of setting the time to 600 ticks, it sets it to like, 3000000000 ticks. There's no delete mode nor a game mode button and the item list is blank saying at the top (0/0). An error report was sent to the Tekkit Lite file. There's something wrong with the bq and bu class file and the log says that NEI is 1.4.5.

Try updating your Java. The version you have is pretty old.
