Hi everyone!

I want to use the nwcommands to do some social network analysis and encountered a problem. I installed the nwcommands and the process seemed to go well. But after installation, no matter what network command I entered, even something as simple as "webuse + some network data" the invalid error is always reported. I uninstalled the package and installed again, but the same thing happened. Here is a snapshot of the error return.

I wonder if anyone encountered the same problem or have any idea about what is going on here~ Really many thanks!

Best,
Jingyuan
