Perhaps navicat has issues with large files, or you don't have enough ram allocated to the VM.
You could try doing it from command line.
Go find mysql.exe (probably in your mysql\bin folder), navigate there through command prompt and use
Code:
mysql -u username -p databasename < path\to\import.sql
Or, you can just copy the dump to the folder containing mysql.exe and import it the same way without worrying about the path.
