Okay guys I found out how to get this working! All you need to do is download java 8 (
)
After that I was able to open the program, it's pretty simple. It just has a statusbar in russian saying (translated) "Injected to browser: false" and "Drop gate".
I was able to skip a few waves, but it's not very fast because you have to wait about 5 minutes until you can reconnect.
Thanks for the tool!
