ERROR #233

I had version 4 running. However i observed that updates did not work any longer.
Checking the website shows the availability of version 5 - compliments for the continuing efforts.

I however still have the same error.

The error message is:

2015-03-03 20:25:02 com.robcole.lightroom.ExifMeta ERROR ****** ERROR #233: Update Photos terminated prematurely due to an error - [string "Common.lua"]:794: Unable to get formatted exif metadata from file (C:\Cache\Lightroom\Import\2015\02\_DSC9912.xmp), error message: Error executing command: Unexpected exit code (4294967295) returned by command: ""C:\Users\Rene\AppData\Roaming\Adobe\Lightroom\Modules\ExifMeta.lrplugin\exiftool.exe" -l -X "C:\Cache\Lightroom\Import\2015\02\_DSC9912.xmp" > "C:\Cache\Lightroom\Import\2015\02\_DSC9912.exif-meta.xml""

what to do?
