I just downloaded the Beta1 release of the new GNS3. In the previous Alpha releases, I never had the problem I'm going to describe below. When I use a c7200 router and connect to an ethernet switch I get 2 error messages : 1.Server error [-3200] from 192.168.56.1:8000: R1: VM R1: unable to enable NIO for slot 0/0
2.Server error [-3200] from 192.168.56.1:8000: R1: VM R1: unable to add binding for slot 0/0.
Anyone with any ideas on how to correct this. Thanks
