Fan and light suddenly wont work.

I bought a house last year (1920's) it was owned by an electrician.It has a hunter fan/light. The wall switch has a guard on it so not to be used to turn on the fan. The fan is controlled by a remote.It was working fine until 1 week ago. I went to turn it on and nothing happened. I changed the battery in the remote first. Then I saw the little switches in the remote and started moving them in case one moved by accident since I last used the remote.It did not work still. Then I noticed the remote was a Hampton bay remote and not a Hunter remote. What next????
