Same problem. Reinstall the game started again 3 times, no achievements.

I had this same issue but I fixed it by running the game as administrator, if you don't know how to do this, here's how:

Go to the game's local files, I did this by right-clicking on the game in my steam library, clicking properties, went to the 'local files' tab then clicked on the big 'browse local files' button.

Then right-click on the game executable file, which is the file that opens up the game (it's icon is the game picture), then click on 'run as administrator'.

A message should pop-up asking if you give permission for this application to alter your computer, click 'yes'.

As you unlock achieves, they won't pop-up in-game, in fact even the steam overlay will stop working even if it's enabled, BUT they will be unlocked within your steam profile with correct timestamps

Just read your post. I will try to see if this will work.

Running it in compatibility mode worked for me too

Works well! Thanks a lot for the tips! :)

I have no problems with achievements whatsoever.
But I am always logged as an administrator, probably that is the solution.

tried admin and compatablity mode to no avail :(
