Real time VI just runs once when using FIFO (Labview FPGA)

Hi guys.

 

I am wrestling with simple problem, I have NI 9211 on my cRIO chassis (9014). I want to collect tempreture data with high frequnecy (let's say 2000 Hz). I have couple of question:

 

1. searching here and there I realized that FIFO method should be used for this sampling rate. Am I right?

 

2. I made a FPGA and RT VI, but the problem is when I click to run the RT vi, it just runs once and then stop (I don't see any error)! I am using the parrarel method explained in the forum, to use the remaining elements in the FIFO and feed them to another FIFO read. (this thread: http://forums.ni.com/t5/LabVIEW/Error-50400-occurred-at-Invoke-Method-FIFO-Read-in-Host-vi/td-p/881453)

 

I am very confused about this FIFO thing, and any help/explanation would be appreciated.

 

Attached is my FPGA and RT VIs.
