Hang download before the final boss in the second part (Crash Bandicoot N. Sane Trilogy)

Passed, and the first and third to end without problems
Began to take a second, I even through an extra floor, I decided to finish the game and hang download
All the levels work except the final
The game pirates(caus), put off the antivirus in the compatibility modes and administrator rights was launched, did not help
Faced with who?
