Install Lightroom 4.4 - where to download the install/ update

Hi,

i have Lightroom 4 and want to use it on my Mac.

When i install Lightroom, i don't have the actual version on my Mac, so Lightroom tells me, that i should download the current version, which would be 4.4

Problem with the version is, that sometimes Lightroom crashes and so i want to fix this...

So I asked Lightroom to search for updates and the result is: there is a newer version, which is 4.4

When i clicked it, i got on the adobe homepage. There should be the option, to download the install (i m not sure if you should be abled to download the update or the install for the current version).

Now there is the real problem.

For Lightroom 4  is a download for windows possible, but under the option Mac OS X, is just the possibility "contact support", and while follow all the instructions i landed here.

So I ask here kindly for help, where i could get those file or if there is another option to solve the problem.

Thank you!
