Truculient IE VUsers get stuck at Init state

Hi Gentlemen,

I have developed a Truclient script and it works find both in Truclient IE script developer and my local controller. The problem occurs only when we try to run it in ALM - Performance Center 11.52. All Virtual Users get stuck at "Init" state and never proceed to "Running" state.  

I try to download RawResults.zip and investigate what's the issue but it does not show any error as the total number of VUsers running were zero.  

I am not an expricenced performance tester and I would really appriciate it if you assist me to troubleshoot this issue. I thank you in advance.
