Post Gain Problem [Archive]

I have had severe problems with the post-gain in BeSweet ever since I upgraded to RC2. Whenever post-gain is activated it gains the files up about 4-5 times more, and also turns the mp3 file into pure noise (I have a sample if you would like it.). I made sure that it was a post-gain problem by testing with and without post-gain. The problem only appears when post-gain is applied. Attached are the logs for the two tests.

Using Azid for gain:

Note the 76.2dB difference in gain. I am pretty sure it isn't my comp as I tried reinstalling BeSweet, and also rebooting before I tested again.
