The starling-navigator was a bug fixed on the current version.
Older game starts are unfortunately not fixed, in this situation you need this command: player.additem 101e9bb 1
The squares is (as already discussed by urst and Kermit61) a language problem, whether in the game or in connection with other programs such as Windows. At the moment I don't have any other solution than the suggested ones.
English or german Enderal and an original english/german Windows operating system do not have this problem.
Maybe a solution is known in the Russian forum?
