SQL 2005 Upgrade to SQL Express 2008

I've run into a bit of an issue while trying to upgrade SQL Express 2005 SP3 to SQL Express 2008 R2.  It tells me the SQL 2008 R2 feature upgrade failed.  Running the report advisor, it tells me the full text search has changed in 2008, but no details on how to resolve the issue so I can continue.

Any advice on how to proceed?  Needless to say, I'm not a database guy, so this is all new territory for me.

Thanks!
