I checked both files the date and size is correct.

I install it on my office PC and reproduce the same problem and error log.

I attach the dxdiag file of the office PC. (scroll down to see download link)

I found 6.59b beta same, cannot use Project Manager, as well as cannot push down the Camera Move button.

It is strange that if I copy the lite-c beta wdlv.dll to A7 folder, the Project Manager works.

Another problem:
I move the .key file to another folder, then start MED it prompt trial expire. I move the .key file back to A7 folder, and I can't launch MED now, it keep prompt trial expire dialog. No affect to WED and SED.
