No units in the volume group + network problem

I'm having the same problem as more users (from what i've read). I installed the trial version of the DSS Lite 6. After that, i tried to configure the volume groups. I experienced the problem with no units available. After that, i tried to enter the activation key. As i did, another problem occured, DSS cannot find my network adapters. Before, it had no problems with that.
I started a new thread, for these problems were not quite solved in previous ones...

what is your setup like ?
are you using hardware raid controller ?
what nic?

I tried open-e on two machines. The latest is a server, I think the main question is the motherboard. I'm using Supermicro X7DWU model.
