Cant update DC112A to latest Firmware

Hi,

When I do a firmware check from within Netgear Genie it says it is the latest (V1.0.0.42_1.0.60) but when I check on the Netgear web site it says the latest is V1.0.0.62_1.0.60 which is 8 updates more. So I downloaded & extracted it & tried to upload it manually it says "This firmware file is incorrect! Please get the firmware file again and make sure it is the correct firmware for this product."

Anyone got a fix for this?

Thanks
