Auto Analysis not working v1.3.37

MP ver 1.3.37 bld 1.1.5917.13431
Pixhawk: APMCopter V3.3.3 (acf2e10c)
MP running on windows 7 environment
Downloaded logs, select “Auto Analysis” and navigate to folder where my log files are stored I get the following error: “Error Could not add reference to assembly mtrand.dll”. After receiving this error message I select OK, and I get the message “Bad input file”. Does not matter if I select log or .bin (bin is converted to log without an indicated error).
