Unable to load 96 well plate data

Hi,
I followed closely the tutorial, and can work without any issue with files containing only one sample.
However, when attempting at loading a 96 well plate .fcs file, I obtain the error:

"[...] UserWarning: There appears to be some information in the ANALYSIS sefment of file [...]. However, it might not be read correctly. u'{0}. However, it might not be read correctly.'.format(self.path))"

Then, regardless of the ID that I call, I can only access the A01 sample of my 96 well plate.

Do you have an idea as to what could cause this issue?

Thanks a lot!
