Error in mirone focal mechanism code

What steps will reproduce the problem?
1. I am trying to plot focal mechanisms using the instructions on this link " 
http://w3.ualg.pt/~jluis/mirone/howtos/Download___plot_CMT_catalog_focal_mechani
sms.html "
2. my input parameters in Global CMT toolbox are as follows: end date is 
1/1/2015, 4<Mw<10, lat 20-30, long 59-70. All other parameters are default.

What is the expected output? What do you see instead?
Expected output is the focal mechanism plot but mirone code is returning error. 
The details of error are as follows:
