Main thread UncheckedExecutionException

[hhues]

I was trying to convert but then this happens.

Exception in thread "main" java.io.FileNotFoundException: world\db\MANIFEST-000016 (The system cannot find the file specified)

I looked and saw that my manifest file ended in mp4a, which was weird, so I got rid of the file extension and got this:

[garvord]

I am experiencing the same error code, when trying to convert a MCPE world.
Platform: Up to date. MCPE 1.2.13, Windows 10 x64, Java 8, update 162.
