MS Documentation has it as

query.Webs = "<Webs Scope=\"SiteCollection\" />";

Instead of:

query.Webs = "<Webs Scope=\"SiteCollection\">";

Not sure if that is what is blowing up your code though. As mentioned above the ID's do look off.


You List IDs are not looking right, Here's an example of how it should be like,

  <List ID="7A9FDBE6-0841-430a-8D9A-53355801B5D5" />
  <List ID="3D18F506-FCA1-451e-B645-2D720DC84FD8" />


If after fixing it, it still doesn't work then try to debug it and find where exactly its getting error.

Hope it helps.
