.lbl file no longer opens

[BenHabermeyer]

Hello, I updated my APT today to newest version (was previously using version from 1-2 weeks ago). The .lbl file of a pre-trained CPR tracker no longer loads in the GUI. When I select file->load project I get the following error message. It appears that the DLBackEnd class object cannot be loaded? I tried on the previous version I had and it opened just fine.

Here is the full MATLAB error message.

Hey Ben, That's strange, I can't reproduce this or see why this would occur yet. If you haven't tried this already, can you try killing your MATLAB, restarting, and trying to load your project again? MATLAB monitors your local filesystem and the object/class system can sometimes get confused if there are any changes.

Another debugging point, at any time after the 'StartAPT' command, running which DLBackEnd in MATLAB should return the m-file at \<APT>/matlab/trackers/dt/DLBackEnd.m.

seems like I cloned the repo and default branch is 'develop' which doesn't have the /matlab/trackers/dt directory

cloned master and loads fine, marking resolved
