CRM 2011 List Component does not work

I had a lot of trouble getting the list component to work on my Dev Machine, I eventually managed to fix the problem, so in the hope that this might help someone please try some of the following steps:

• Ensure that CRM is running under a domain account with access to the sharepoint site where you plan to install the CRM List Component, see my other post
• Try creating a new Sharepoint Web application
• Install the List Component.WSP in the Sharepoint site. Go to site settings -> Galleries -> solutions. Activate the solution. This one was hard to solve. Try the following:
• Ensure Sharepoint Foundation Sandboxed code service is running ( found user central admin -> System Settings -> Manage servies on the server.
• In Manage Applications, select your application - select General Settings (ribbon), make sure that Browser file handling is set to permissive.
• reset iis
• if you get the error that user code service is too busy, restart the service and try again.
• Finally and this one was the hardest, edit your hosts file located at system32\etc. add the following entry 127.0.0.1 crl.microsoft.com. I found the soluation here

That's all i can think of now. Good Luck!
