Materials Database compatibility

We recently upgraded to 2011 and I went to load up one of my '09 models and re-run the flow simulation only to find out that my custom materials were all gone.  I went to the file locations setting and made sure the correct folder was in the list.  I tried moving it to the top of the list and then made it the only entry in the list.  It seems that flow simulation no longer recognizes any of my custom materials from previous versions.  This is infuriating.  If they are going to break compatibility, why not provide a conversion utility?  In our line of work, we use material properties that are not in the pre-defined database so this is a real problem.  Re-entering all this manually is a waste of time and money.

Has anyone else on here had an issue with this?  If so, what was your solution?

Thanks,

Rich
