Also i have synchronised in the properties and it downloaded something, but still doesn't work.
Probably i don't have some required packages, but on the owner site i couldn't find it.
You can clear the blueprint cache from the Tools & Docs tab of the RW2 launcher app.
What you would be talking about with synchronisation is the Steam Cloud. This stores your scenario completion data (ticks/crosses) for all scenarios, scores for career scenarios and Steam Achievements for career scenarios. The advantage is that it then synchronises that data to any computer you are playing on, but I do remember a couple of anecdotes from people who swore that turning it off fixed all kinds of issues (none of which made sense).
