About to get myself into trouble

Hello all
Currently working on my toy ride. A '97 Trans Am, with only a few bolt on mods. I'm changing rear end, and will obviously need to update the tune (2.73 to 3.73) for the speedometer and I assume shift points.
Bought the Jet DST, and can't wait to screw up the tune on my first attempt (sarcasm here?). I do have a spare computer just in case though.

Wanted to download a couple of stock .cal files from this site just to check out the software, and don't seem to be able to. Windows 7, ie 11 and clicking on an attachment, ie tries to download the .php file instead of the .cal. Any tricks you can suggest?
Thanks in advance.
I'm sure you'll be hearing from me soon.

I just clicked on a few 1997 .cal files and they wanted to download as .cal files just fine.

I have the same issue when clicking any type of file to download it they all download as a .php file regardless of whether it is an .adx or .bin etc..... I just name the file what I want and save in the right directory then change the extension from .php to whatever it needs to be after the download is complete. You get a warning from windows when doing so stating that changing the extension could make the file unstable, but that is a precaution for those that might do so by accident. I haven't had any issues with files that I have downloaded this way as of yet other than the inconvenience of having to change the extension. I'm running windows 7 and internet explorer 11 as well.

IE11 --- Right click on link and save link as should solve the problem. Or change to firefox and it just works like it is supposed to.
