Virus TI2 with access Virus, Glitches when it loops and has serious timing issues...

I am running a macbook pro 2.5 GZ OSX 10.5.8 with live 8.1.3 and Access Virus Polar TI2 with the latest update and I am getting a nasty glitch wherever I loop midi info 2 4 8 or any bar loop point. I am running at 128 buffer size but I have increased it to 1024 with no difference. WTF? The timing issues are unbearable above 128 buffer size, but this glitch is equally unbearable. WTF? Any one have this problem, and more importantly , how do ya fix it?

And what the hell is this beginner crap under my name...
