Change in MARS OpenDAP URL

To whom it may concern,
I am looking to conduct a larval distribution model for the Bay of Biscay area. As such I am attempting to use the MARS 2D openDAP configuration in ichthyop. However, it appears the default location of retrieving the online data has moved. It is now longer on http://www.previmer.org/previsions/courants/modele_mars3d_manche_gascogne. It has moved to http://marc.ifremer.fr/resultats/courants/modeles_mars2d_atlantique_nord...(typevisu)/map/(zoneid)/manga#result_infos0. 
However, I am yet to get run a successful preview of the area in ichthyop. I am currently setting the Data URL to http://tds1.ifremer.fr/thredds/dodsC/MARC-MANGA700-L1_MARS2D-FOR_FULL_TI...
Upon selecting all of the variables I receive the error

Please, could you advise me on where my error is coming from?
 
Many thanks in advance.

Ichthyop version: 
Ichthyop 3.3alpha
Hydrodynamic dataset: 
MARS 2D OpenDAP
Java version: 
Java SE 8
Operating system: 
Windows 10

In the configuration menu for MARS 2D OpenDap, make sure the URL is
http://tds1.ifremer.fr/thredds/dodsC/MARC-ATLNE2000-L1_MARS2D-FOR_FULL_T...
 
In the configuration menu for MARS 2D OpenDAP, click the box labelled "Show hidden parameters"
Make sure that the Dimension in the latitudinal direction is          nj
and that the Dimension in the longitudinal direction is:                 ni
Also check to make sure that the other variable names are the same as in the OpenDAP url display:
Dimension in time:  time
Bathymetry at Rho points:  H0
Latitude of Rho points:  latitude
Longitude of Rho Points:  longitude
Averaged time since initialization:  time
Zonal velocity:  U
Merdional velocity: V
I tried it with these settings and it worked. 
The default ichthyop setup has the lat and lon dimensions named wrong for this model. The MARS 2D model is on a non-linear grid so there are dummy axis variables ni and nj that point to 2D longitude and latitude grids, and to the U and V grids.

Thank you very much. That has solved my issue. I look forward to using your software.
