I received emails this morning from a few of you saying the TAM1223 file was bad. Can't tell from the emails whether or not you were referring to the .MCP file or the .DRF file.
I just downloaded the TAM1223.DRF file from the Brisnet site a few minutes ago and it appears to be ok.
Don't know whether or not Brisnet had a bad file up initially and replaced it with a good version...
But if you were having problems before -- I'd suggest going to the Brisnet site and downloading the .DRF file for TAM1223 as it appears to be a good file.
