GNS3 1.3.10 Server error [-3200] from 127.0.0.1:8000: SW1: unable to create generic ...

I upgraded from windows 8.1 to windows 10 upgrade and upgraded GNS3 from 1.3.1 to 1.3.10. 
After the upgrade none of my virtual box machines would connect to GNS3

I solved it by connecting each  virtual box machine via  GNS3 Virtual box;

1. From GNS3 edit then preferences

2. under virtual box VM click virtual box VMs

3. click new

4. choose the VM you want to connect to

5. check the network settings are correct and make sure it selects the correct network interface

6. click apply and o.k.

7. go back to main GNS3 under host you should have the VM machine you want to connect to

8. drag it into the network

9. got to virtual box settings and make change the VM network setting to not attached and make sure cable connected on the advance settings

10. start the host under gns3 (make sure you do not start the VM yourself)

11. GNS3 will now start the VM for you

12. ALL SHOULD WORK!
