ReadMe: KeyNotFoundException

The old bug that was causing KeyNotFoundExceptions, related to how the server uri was specified has been fixed in the March 24, 2008 Pre-release http://www.codeplex.com/tfstotfsmigration/Release/ProjectReleases.aspx?ReleaseId=11952
Everyone should be using that version (or newer).

 Many people are still getting KeyNotFoundExceptions during their migrations.  This is because there is another (previously unknown) bug that causes the same exception.  This bug is caused by the GUI reloading the migration configuration file on a separate thread.  Once in a while the migration is at the point where it is accessing the list servers, in the time span between when the 'old' migration configuration was cleaned out and when the 'new' one is ready to be used. At this point in time the server list is empty so the migration halts. 

When the GUI detects that the migration process has stopped without finishing it should automatically restart it. So this should not be a blocking issue.
