Trial Balance Setup & Trial Balance Import is not working

[Sameer]

I tried importing trial balance into ProSeries, it doesn't work as expected
Once I select the required file (txt/dbf) the data in it doesn't get input ( P&L/balance sheet doens't gets imported) 
it always shows link accounts to tax line, tried CTRL+L as described, it doesn't work

Please let me know how to fix this.
