This site http://www.teahlab.com/ looks like it has lots of really useful stuff about electronics but the STUPID JAVA isn't working. It worked before when it said my plugin was out of date I pressed "run this time" (though that was quite annoying as I had to do that every time that I changed page.) Eventually I decided to update my java so I did and then I went back and it did not work. I then tried re-downloading the (slightly) old version of java and when it tried to remove the old one it said that the .dll files were missing from my computer. After that, I tried restoring my computer and I went back on and it had the old java and asked me if I wanted to update my plugin or run this time and nothing happened. (When I restored I did not scan for affected files so that might be the problem.) I then tried doing the first bit again (failing to delete the old version and trying to get the new version) and it still does not work. HELP!!!!!!!!!!!!!!!!
