So I had this network which topology is this:

And I had OSPF up and running and everything seemed to be well. I fired up a windows 7 32-bit host machine under Switch1, enabled port 2, added vlan to it as untagged and suddenly Switch1 gave this error:

I shut down the host and rebooted everything, and everything was fine. I fired up host once again and this same error occurred in under one minute. I rebooted everything once again and took the host down so the situation would calm down.
Now I noticed in Router1 had my VR and vlan "internet" removed?? I had "vr-corporation" and everything under it. Both default vlan and vr-default were "disabled". Now I watch Router1 configs and everything is preserved but vlan "internet" and vr "vr-corporation" has completely vanished. I tried to load my configurations again but they did not appear.
Now I tried to load the configurations again and it only says:
"This command cannot be executed during configuration load."
What is happening??
