Thanks for reporting! I'll check this.

As a workaround please run in console java -jar app.jar -c. It will clear settings and then you can continue using application as usual. Let me know if it doesn't help :)

Further tests indicate that this happens when the last folder selected no longer exists this error is thrown.

Yeah.. There were #79 and #81 about the same thing and it's fixed.. or should be fixed already. And it looks good in code and it works well on my linux and win10.
Maybe something wrong with particular JRE version (because I have quite a bit newer ones). Will check with the one you mentioned a bit later.
Thanks =)

作为解决方法，请在控制台中运行java -jar app.jar -c。它将清除设置，然后您可以像往常一样继续使用应用程序。如果它没有帮助，请告诉我:)对我这里来说并没有解决，依然还是选择不了文件

The Error is still there with v7. I had to do the trick with "java -jar app.jar -c" to reset the settings.

Did I do right? Can't seem to work it around

[developersu]

@Milo5789 this command removes application settings. So app.jar should be replaced to jar file name you downloaded. E.g. ns-usbloader-7.0.jar. Also before executing this you have to change folder. If you saved jar file on your desktop, you have to do the following:

cd Desktop
java -jar ns-usbloader-7.0.jar -c

Hope it helps!
