I tried running Lokad again, this time I got an error
message stating: "Exception of type
'Lokad.CallCenter.Common.ValidationException' was thrown". However, after
this error message was displayed (in the Loading "progress bar"), the bar
continued to fill. When the progress bar got about halfway full, it began
again from scratch and then it seemed to freeze up (similar to the problem
I
was having originally).

Tried it again, this time using a calling period of only 2
hours (9AM-11AM) in hopes that the reduced "workload" might help. This did
not seem to have any positive effect.
