I have downloaded the FMS from the FileMaker Developer Subscriber section (fms_22.214.171.1248.dmg). But when I open the dmg I get a checksum failure. I tried the download with two different computer (MacBook, MacMini) with two different browsers (FireFox, Safari), always with the same disappointing result.

I hope you can fix this soon.
