Hi Andrei,
I wonder if the user name or account login migh somehow be one thing causing this. At any rate, it does not surprise me. It might be more efficient to export the project and import it on the other pc. (File-> Export) Are you using revision control?
Have a look at these wikis and please keep us informed.
