Hi,
I have the same problem with eNSP that other people. I start the program but windows says there is a problem an the program will close.
I've try the solution loctdr /r, and it works parcially, because i have to do it at the same time that the router is starting, and i have to do the same with every router in the topology.
Do you have a total solution for this issue? I know is a beta simulator, but i think this is a big bug!
Any way, congratulations for eNSP!, i was waiting for it!
