Have you tried 'REPAIR TABLE virtual_aliases', etc?  The data files  
may be fine, and MySQL may be able to fix whatever is wrong with the  
FRM file for you.  Worth a try if your next step is to drop and  
recreate.  If it doesn't work, you're no worse off than now.  Good  
luck, and let us know how it goes!
