alter-table

Can someone explain to me why I am receiving the following error?

I want to rename the column "exerciseID" to "ID" in a mysql table using the following syntax.

ALTER TABLE  `exercises` CHANGE  `exerciseID`  `ID` INT( 11 ) NOT NULL AUTO_INCREMENT

However I receive the following error:

MySQL said: 

#1025 - Error on rename of './balance/#sql-de_110e' to './balance/exercises' (errno: 150)

Any suggestions would be much appreciated
