FAST Search : Unable to display this Web Part.

Hello ,

I have configured FAST Search on my farm using SP 2010 Beta version but getting the below error :

Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator

My farm configuration is as below.

Operating System : Windows Server 2008 SP2 on all the servers

Database : SQL Server 2008  (10.0.2746)

I have one Admin FAST server and one non admin Fast server, SP 2010 Beta is installed on different server in same domain.

I am following the deployment guide at http://www.microsoft.com/downloads/details.aspx?FamilyID=A65AEF6F-BC99-4B29-81BB-37FCE8AD6EA7&displaylang=en

I have uninstalled and unistalled the components twice but still getting the same error and also went through the thread 

http://social.technet.microsoft.com/Forums/en-US/sharepoint2010setup/thread/f653c63c-34ff-4215-bfbc-17d3d26bd6c9/ to make sure all menotined is in place. Will appreciate if there is aAny pointers to check something I might be missing.
Some observations :

1.       I was not able to configure on the non Admin FAST Server because running the command  “New-FASTSearchSecurityClaimsUserStore -id win” gives error

New-FASTSearchSecurityClaimsUserStore : Unable to create new Claims content: Could not connect to net.tcp://localhost:13278/ConfigManager. The connection attempt lasted for a time span of 00:00:02.0252610. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:13278

2.       The manual creation of folders data, data\data_security , data\data_security\admin , data\data_security\worker  was done on both FAST servers

3.       I can bring up http://localhost:13280/ on the admin server but not on the non-admin FAST server

4.       Result of Get-SPEnterpriseSearchExtendedQueryProperty -SearchApplication "FAST Query SSA"

5.       All the farm components are in the same domain (Mydomain) and so is my account while I am trying to query.

6.       On AdminFastServer In %FASTSEARCH%\var\log\syslog\ QRProxy_AdminFastServer.log found the following Information:
