When you attempt to start the CMS server or start SmartServer, you get an "Automation Error - More Data Available" error.

One of the values in your registry is probably corrupt and most likely it is related to the string values in the key:

HKEY_CLASSES_ROOT\CLSID\{20708EE2-24E3-11D3-AB5C-D41203C10000}\InprocServer32

When you inspect the values in this key using the Modify Binary Data feature in RegEdit, you may notice extra data that is not shown when the value is viewed in text mode. To resolve the problem, you can delete the value and manually enter the original string value as you saw it in text mode.
