Got the exact same problem here =*(
TO THE MINESHAFTER TEAM:
Looks like the link is down guys, or the script within it or whatever XD
I reinstalled java and flash hoping it was somehow maybe using it, but i had no luck in finding a solution yet.
Please take a real look into it guys, think me and Gus here aren't the only ones with this problem, just too many people don't know where to look to fix this!! :)
Thanks in advance for taking your time to read this, and i hope this issue can be resolved soon, Got the urge to look unique.... :P
Cya around, and Happy Mining ^.^
