You should be able to get the software for it from the URC web site as long as it has a valid serial number (located inside the battery compartment).

The seller should have the software for you. The seller may even have a copy of the LiveUpdate-able software for you. Ask first.

Also, ask if there is a valid serial number. If there isn't, don't buy it.

If the seller does not have a LiveUpdate-able version of the software for you, you will be able to download the latest non-Live Update-able software (again, if you have a valid serial number.)

If you have any problems, just call URC's toll free number.
