Error when running "Fix" duplicate nodes with Validator Plugin

[julisonbr@…]

I'm using Validator plugin in JOSM, in a Windows Vista OS. I changed some ways and it show me some erros related to duplicate nodes. I double-clicked in one of the errors and it selected the two nodes duplicated. I clicked in "Fix" and then I got an error:

The Validatator version you are using doesn't match the JOSM version you are using. You trying to insert a CD into a floppy disk drive, so to say ;)

Please update both JOSM and your plugin. That should fix the problem; if it dosn't, please re-open this ticket.
