Welcome!

I fixed the issue by downloading and updating to Java v8 u77. Thanks for your help.

I have the same error. Any help would be appreciated.

This is one of the stupidest things I have read in a long time, so I have to give my two cents. Donations are not payments. If it was, you would have to pay to access Runemate. When you donate to a charity, do you expect anything in return? The API of Runemate is huge which helps the developers...
