ADS data items giving error in citi file

Dear All
This might be a simple issue but this one is driving me nuts. When i use the older version of ADS before 2008 i can successfully simulate S parameters out of measured 2 port CITI file by using data items, But when i try to simulate S parameters out of measured 2 port CITI file in ADS 2009 it gives me this error. Can anyone suggest what is going wrong
PS: I set the file type to CITI in "DAC", "S2P"

Would you upload you schematic file? I don't know what's error from only the error message.

Thanks tony
Please find the attached dsn and citi file that i am trying to simulate

hi, I have just tried running your file using ads 2009. it runs but only gives a warning about the citi file. no errors.

thanks mkonca
I dont know what is the problem it is not working at all in newer versions i tried it in ADS2009 update 1 and it gives following error
"error detected by hpeesofsim during netlist flattening
While evaluating expression 'SNP1.CMP1.ALL:
Invalid S22 Parameter name detected"
Can any one else try to simulate the file

Since its complaining about a parameter name, why don't you try opening a completely new project and doing it from scratch. May be it won't give you the error then.

@mkonca
Thanks
I tried to do the process from scratch with a new file but still the same error
Any other suggestion!

i'm encountering the same error too.
