Pyradius:First, try a View-->Refresh Data with the chart open. If this does not resolve the issue, close any open charts, browse through Windows to C:-->MetaStock Data-->Data On Demand Cache.
Delete all the files in this folder, but leave MSSMART. Go back to MetaStock and try accessing the symbols again.
