Very poor support
Becomes obsolete very quickly, no online updates. In this case I was not even able to reinstall it after some time as it has passed on to other publishing houses which have different (hectic) unlocking procedures. The email I received involved: giving them a code, my personal wifi address, snapshots of my purchases and then no one even bothers to reply. This has to be repeated every single time you want to reinstall it!
