I can't open simulink block library. I get the spinning wheel at my mouse but nothing happends (I have waited 30+min multiple times). Just 2 days ago everything worked perfect. I installed latest windows updates and google chrome and after that the help functionality didn't work in matlab/simulink. I tried lots of things to fix it eventually found a solution but wanted to restore matlab/simulink to defaults by reinstalling it to be sure everything was all oke again. But now the problems are worse and even reinstalling doesn't fix it.
I tried: uninstalling matlab 2015b (all tools). removing all leftover files (and also did a register scan with CC cleaner). reinstalled matlab 2015b. still not working. (tried it multiple times)
Also HELP doesn't work afther a fresh install but I managed to fix that with this command.
com.mathworks.mlwidgets.html.HtmlComponentFactory.setDefaultType('HTMLPANEL');
Also tried these commands:
restoredefaultpath
savepath
rehash toolboxcache
I don't know what else to do (I'm considering reinstalling windows just to get matlab/simulink working again I need it to finish a project).
I'm running Windows 7 64-bit (latest updates installed) and matlab 2015b-64bit.
when I press ctrl+c I get this message and the library opens after all, but I do not trust using it

Hi Tom,
This could be a known Java 7 issue where an operating system's IPv6 configuration prevents IPv4 loopback. That fails connector startup. A common workaround is setting "java.net.preferIPv4Stack" to "true" so JVM checks IPv4 first. The setting may be applied through java.opts or _JAVA_OPTIONS.
Some relevant links to get you started:
Hope this helps!

Hello, thank you for your answer. I already did a reinstall of windows so I can't try your solution. Everything is working correctly now.
