INTERNET is not working while VPN ON

Here is a sample LAN-to-LAN vpn configuration between 2 IOS routers:

http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a0080194650.shtml

and yes, it works the same as NEM.

You can downgrade it by just tftp the image to the router, and configure the "boot system flash:"

Then "wr mem", and reload the router.

I would recommend using a standard ACL for your split tunneled ACL
