Jon, version 8 is a very old program (2009?) It is no longer supported and is not compatible with a number of current web standards. If you must use it you will need Incomedia to assist in unlocking it. You will need to make a request here and provide whatever licensing information you have. 

If you do this, mark your first post as private (click on the eye)

Can I suggest that you use a new version?

This has a limited feature set but it is free (& I am pretty sure the features that are included will be far better than those in Compact V8)
