FTB launcher issues (launcher bug)

[bvoice360]

Whenever I try to open ANY modpack, I get the normal code (at first) in the Console, but then this error appears in the lines of code:

java.io.FileNotFoundException: \FTBLauncherLog.txt (Access is denied)

Then, later on (after a lot of lines of non-error code), the entire STDERR section on any modpack becomes one giant torrent of red errors (these errors are for the MindCrack pack):

I then get confronted with a black modpack window.

Anyone have any solutions?

P.S.
why did I find THIS in the code!?:

First follow the recommended setup guide. Then if you are still experieincing problems click on the 'Paste my log to pastebin.com' button on the console. This will create a link, pastebin.com/xxxx, at the bottom of the console that you post here for us to look at your log.

This can be turned off in the Options tab. Click on the 'Advanced Options' button and check 'Disable Google Analytical Tracking'

The guide didn't cover my issues, so here it is (this is in debug mode/view for the Mindcrack pack).
Seems it's not just my antivirus hating the tracker (plus the other 5 on the page you are viewing now).....

This is a bug with one of ChickenBones CoreMods it would seem, a strange one too. Force update the modpack and if it happens again, paste the new log.

I tried that and it didn't help, so: http://pastebin.com/xLqgwub2

Also, it keeps re-enabling the tracker even when I 'disable' it in Settings

Any suggestions as to either?
