Gradebook crashes on Mac Mojave upon second use

Hi there,

My Gradebook app will only launch correctly once on my Mac (Mojave) from the launchgradebook.jnlp file that is downloaded inside of PowerTeacher.


Every other time I try to launch it, including if I redownload the .jnlp file, it crashes after I enter my username, password and then try to sign in. It gives me a problem report explaining the app quit unexpectedly. 


I have tried going to the Java Control Panel and deleting the temporary internet files, but this didn't work.

I also tried deleting Java and reinstalling it. That did not work either.


The only thing that fixes the problem is reformatting my Mac to the factory settings, reinstalling java and redownloading the .jnlp file. This unfortunately only works for the first time I launch the app and then I can never get back in if I want to close the app and try to use it again later. 


I would greatly appreciate any help because it is incredibly frustrating having to keep reformat my mac for just one single use of Gradebook.

Thanking you in advance,
