something seems off, I was able to play for a bit then this started happening.

Looks like there is no java installed in your browser.

installing again, but idk how I lost my java I was playing mid game before it went crashy on me and I started getting this error.

Edit: still getting the same message, even after reinstalling java.

Verify Java is enabled in the browser if you're going to use the Java Web Start launcher.

To note, that's not the exception that was thrown. The error window gives the XML file used to launch Java in one tab, and then exceptions in additional tabs.

Java Control Panel -> Security Tab -> top most -> check

For other browser than IE you'll have to go JCP -> Extended -> third colum and check there
