Hello all.

Just saved my project in Analysis 2.0.5.  I had some spectra that  
couldn't be found (this wasn't a problem in 1.0) and now when I try  
and open my project I get the following error:

Project invalid, please quit, fix and re-start:  ValueError: empty  
string for float()

Here is the traceback

 >>> Warning: spectrum (T1_b_0, nmrPipe): data file None not accessible

    levels = getSpectrumContourLevels(spectrum)

    levels = [float(level) for level in  
levels.split(spectrum_contour_separator)]

Any ideas on how to fix this.
