error while running relax-GUI tutorial -- November 18, 2014 - 00:07

Hello all,

I was using the GUI version of the software to run the tutorial available
in the manual for analysis of relaxation dispersion.
When i execute the run I get the following error

RelaxPipeError: RelaxError: The data pipe 'R2eff - relax_disp (Mon Nov 17
10:50:08 2014)' already exists.

Not sure where the error is arising from. Any help is greatly appreciated.

Thanks
