I had the same prob when I updated, 2 version 4.7 and 2 version 4.6. It also showed that ASPI wasn't installed correctly so I just deleted those 4 files and reinstalled. Came out perfect.
Also in the readme file they tell you which files have to have the same version to be working OK. Turns out it's OK to have 4.6 and 4.7 files.
