Hi Kyler1994,
Try cleaning your Java cache.

If this didn't help, please run RuneMate using a BATCH file.
This will allow you/us to view debug information to easier identify the issue.
First off all, put RuneMate.jar on your desktop.
Simply open up notepad, and paste in the following:
Save this as
RuneMate Debug.bat on your desktop.
[Make sure when saving you've selected Save As> All Files]
Then simply run the batch file, and try to run a bot.
Make a screenshot of the debug dialog, and post it here.
Best Regards,
Microsoft
