Plate Solve 2 libraries

I am having problems with which library PS2 uses. Earlier in the night I ran two practice sequences that successfully slewed and synced on my targets. I then set up SGP to wake up at 1:12 and start a new sequence. It calls PS2, PS2 appears to start the solving process correctly, but it returns an error:

PlateSolve: APM file found, but could not not be opened.

The successful plate solves that I did earlier in the run did not indicate which library they were using, so I have no idea why it is choosing APM, or why it can not open the files. I was asleep at the time, but Clear Skies indicated the conditions were excellent. My files are at this link.
