Did you try to install the opensand and opensand-manager meta-packages 
while the version 2.0.0 was already installed ?
If this is the case, only the meta-packages were updated and not the 
entire platform. To update the version with meta-package you need to 
uninstall the previous version first.

Can you reconfigure you collector (dpkg-reconfigure opensand-collector) 
and correctly set the interface name for service publishing if this is 
not already done ? (this should not change anything but there was a bug 
in previous versions that may be still there in some cases).

Can you ping collector from satellite and terminal ?
Can you send me the opensand-collector and opensand-daemon logs on the 
appropriate machines ?

With physical layer, the MODCOD is chosen according to emulated link 
budget then, either you need to increase your nominal conditions between 
GW and ST1 to get a higher C/N0, or you need to allow others MODCOD for 
the terminal (in advanced configuration, 
global>down_forward_band>fmt_groups add MODCODs separated by ; or range 
of MODCODs separated by -. To enable all MODCODS on forward link simply 
add 1-28 instead of 28).

You're welcome.
