A file association of some sort...
What is it that you are clicking when you try to view the drum loops: an icon, a shortcut, a filename? Do you want the loop to actually play?
Do the drum loops filenames have their own unique extension? I saw a couple of links that indicated .wav or .mid by just searching for drum loops. Does MTPDK2 use one of those extensions or a proprietary extension?
When you click a drum loop file the extension part of the filename is used by Windows to launch the applicable application software.
If the applicable application is no longer installed then some default is being applied and you see the partial image. The partial image is somehow also be tied to the file name extension.
You can change the default associations:

And there is also the possibility that Reliability History may be capturing some error code, warning, or even informational event when the view/play attempts are made.
Also look in Task Manager and Task Scheduler just to ensure that some remnant of MTPDK2 is not lingering behind.
