Not sure if this is the place to report this or not.

I have only just setup GNS3-ER using VB and IOU today. I am running v1.0 beta 1. All I have done so far is setup 4 IOU switches, 6 routers and a GNS3 switch to connect routers to IOU switch. I have not booted any devices up yet, just ran connections from each router to the switch and the inter-switch connections on the IOU devices. I save topology and when I opened it up after closing it I get traceback and exception detected.

Not sure what steps to take.

I have the exact same error after closing and reopening a project with two routers and two switches. After reopening, the switches did not appear.

[EDIT]
Just read this note topic11132.html which seems to acknowledge the error. I did delete some of the default Ethernet switch ports.

This has been fixed now. Please see topic11132.html

Thanks,
