Revit 2010 and 2011 Not Getting License

All of the Autodesk 2010 and 2011 products have a propensity of corrupting the cascadeinfo.cas file. This file is directly related to the obtaining of a license from LMTools. We have found that when Revit can't find a license from the server you need to do the following:

WorkAround

The current workaround it to rename/remove the corrupt CascadeInfo.cas file following these steps.

1.
Return any borrowed licenses
2.
Check in any checked out licenses and exit all Autodesk products
3.
Rename or delete the corrupt CascadeInfo.cas

The CascadeInfo.cas file can be found in the following locations:

Windows XP:

C:\Documents and Settings\All Users\Application Data\Autodesk\Adlm

Windows Vista and Windows 7:

C:\ProgramData\Autodesk\Adlm

Mac:

/Library/Application Support/Autodesk/Adlm/.config

One word of caution. This may cause your corresponding AutoCAD product to crash on startup. We are looking into this and I will post when I get an answer for this.
