I bought the game on steam and somehow i can't receive achievements no more. Any idea of why this happend?
Do you believe you fulfil those conditions?Achievements can only be gained in single-player ironman games started in the grand-campaign. They can be earned while playing older versions of the game as long as the given achievement was present in that version.
It is not possible to gain achievements if the checksum has been changed - either by tampering with game files, using mods altering gameplay mechanics (graphical mods do not affect checksum), or if the game installation has been corrupted. NOTE that running the game in debug mode changes the checksum, rendering achievements impossible.
Yes, actually i had some achievements of the game before the 2.0.3 version release.According to the wiki:
