Connect 1.335 Runtime: The specified certificate path is invalid

Hey everyone, I'm having issues with using a new certificate in Anaplan Connect 1-3-3-5.  The error is "Anaplan API: Could not initialise service credentials (Runtime: The specified certificate path 'C:\Users\KBeltz\Documents\certificate-8936384729097362371525000942346120755' is invalid)" 


@Echo off

rem This example loads a source text file and runs an Anaplan import into a module.

set certificate="C:\Users\KBeltz\Documents\certificate-8936384729097362371525000942346120755"
set WorkspaceId=""
set ModelId=""
set Operation= -export "Current Forecast COP.csv" -execute -get "C:\Users\KBeltz\Documents\Current Forecast COP.csv"

rem *** End of settings - Do not edit below this line ***

setlocal enableextensions enabledelayedexpansion || exit /b 1
cd %~dp0
if not %certificate% == "" set Credentials=-certificate %certificate%
set Command=.\AnaplanClient.bat %Credentials% -workspace %WorkspaceId% -model %ModelId% %Operation%
@Echo %Command%
cmd /c %Command%


Any help would be much appreciated!
