CRM 4 Plugin Names 'blank' after upgrade

Ive found that on a number of occasions when doing an upgrade from CRM 4 -> CRM 2011 (through db attach) that the plugin names/steps appear blank when looking through the plugin registration tool.
A simple UNSUPPORTED sql script can fix this for you. Run this on the crm database (XXXX_mscrm) you want to patch up:

UPDATE PluginTypeBase 
SET Name = TypeName 
WHERE Name IS NULL

CRM 2011- Fetch XML dependentAttributeName error

I kept getting what I thought was a random [InvalidOperationException: dependentAttributeName must be specified] error message when I was doing some 'Deep Queries' on a grid on a CRM Form. I had done a few of these before and was stumped as to why it wasnt working this time. Couple of things to check which helped me out in the end:
1.)Ensure that any relationships you have entered are the correct ones and spelt properly

2.)In the fetch xml of the view you are using to look up the deep query, ensure that the link-entity(s) are used and mapped correctly right up until the 2nd last entity in the chain (last one is done automatically). Also note that if you dont put any link entities at all,it will error out :)
