Problem with spellcheck

[Enrique Saint-Pierre]

Hi: I have LyX 1.5.5 running in Windows XP, but the spellchecker doesn't work. 
I get the message The spellchecker could not be started. no word list can be 
found for the Language "es_ES" I reinstalled Aspell-0.50.3 and 
aspell-es-0.50-2-3. Now it is under C:\Aspell, but this not solve the problem. 
Thanks in advance for any help, Enrique S.
