Need help. LMMS 1.1.3 Unable to load the instrument.Window 8

Having trouble with LMMS? Ask about it here.
Hi! As I mentioned on the heading, I used LMMS 1.1.3 on Window 8.1
I used DSK The Grand - win64 on my project. It was a 14 min long project.
When I accidentally press undo button, everything froze and cannot be recoverable. I was forced to close the program and after that, the project cannot be loaded again.

When loaded, it'll freeze at 45% then force me to close it. After I closed it, the window will pop up the message said "Unable to load the instrument."

I tried creating new project using the same plug-in and it works normally. But I really want my progress back.

What should I do??

Can I some how cancel out the plug-in and get the file back? I'd do anything to get it back.

Yes, that is exactly what you can do:

Its only a few VST instruments, that gives this problem, unfortunately the opposite is the case for effects.
I will add your DSK The Grand - win64 to the no-go-list.
Thanks for reporting!
