I was working in flash builder and a java update poped up and I installed it and now my flash builder wont start
I had same thing. I have installed new fb 4.7 beta instead. It works fine. If you find the solution, please post it here.
ok I solved it
I had to uninstall ALL my adobe products and then use this http://www.adobe.com/support/contact/cscleanertool.html
Then update my java again, then reinstall my entire Adobe collection again!
But it is now working how it should
