Unable to upgrade to 1.9.2.7-7f

I been running version 1.9.2.7-7c happily for some time, but noticed a fix to a bug that I've been working around, so thought I upgrade to 1.9.2.7-7f. So I used the firmware upgrade menu on the webserver from the WAN side. The file is uploaded but then I get the following error message:

Firmware upgrade fail. It may result from incorrect image or error transmission. Please check the version of firmare and try again.

Any idea what the problem is I'm sure the files is correct since the md5sum matches that on the website.

My goof. I forgot you need to upload the trx file in the zip file not the zip file itself.
