problem loading R1, R2 and nOe files for modelfree -- June 27, 2014 - 00:50

Hi,
I am encountering problem while loading R1,R2 and nOe values calculated for
two different fields into relax (precompiled version 3.2.2) for mac 10.8.5.
When i try to add the data and try to change the "free format file
settings" for respective file, it is kind of hanging and does not proceed
anywhere. My files are in the following format,
3       GLY     1.814795542     0.090739777
4       SER     2.267446596     0.11337233
5       MET     2.621469801     0.13107349
6       ASP     2.751590887     0.137579544


Am i doing something wrong? I am following the protocol from this link,

I have attached a screen-shot for the problem. Any help is highly
appreciated.
