VSTAR: Null Pointer b/c Plugins

Hey

 

I am experiencing a strange problem. On a Windows 8, my VSTAR has worked fine until today. THere is a null pointer issue. Tried renaming the vstar_plugins to a different name to see if the VSTAR software would open, but it claims the plugins are currently in use. I am not able to delete the plugins directory, the task manager is not showing the files or vstar in use. Tried rebooting as well.

 

Any ideas?

 

Thanks

Can you do me a favour and try to start VStar from a Windows command prompt?

If you open a command window (aka DOS prompt/shell) and cd into the VStar directory, where VStar.exe and VStar.bat live, then type: VStar.bat

Then can you send me a screenshot or copy and paste the text you see in the command window?

I'm wondering whether there's an exception being thrown that can be seen in the window.

Fixed

I fixed the problem:

 

-- Had to wipe my computer of all other versions of Java

--uninstall VSTAR then delete the plugins library.

 

Then, put everything in the same folder to remove the null pointer error.

 

Thanks for the response :)

Great.

It's odd though, that you had to do that. Sorry I couldn't solve it immediately. It may be that there were multiple JVM processes active and there was some contention over resources. That's pure speculation though. 

I was going to suggest that you try a local installation from SourceForge. That's where the .bat and .exe files are.
