Ben,
in MySQL, only the root or user that created the procedure is allowed to see the procedure source code and hence the parameters. In order to allow myDBR to operate under non-root username, myDBR 1.2 uses new method of determining the procedure parameters. You might have a situation where the procedures are created under another username than what you are currently using to run myDBR (i.e 'mydbr').
In order to fix the problem you have two options:
1. Recreate the procedures under username 'mydbr'.
2. Run myDBR under the same username which was used to create the procedures (perhaps 'root').
If you created the procedures originally under username 'root', we'd recommend that you choose option 1. This requires dumping the procedures from the database (if you do not have them stored elsewhere), drop and recreate them under username 'mydbr'. You can do all this in MySQL Query Browser if you wish.
