using LIne 6 monkey (it's a free download from the downloads link at the top of this page) reinstall the latest flash memory and choose not to keep your presets when it asks you on your PC during the reinstallation of flash memory.  once you reset them though you cannot get them back.  so if you want to, back them up (save bundle) in POD HD Pro edit, which is also a free download from the downloads menu.

after that you'll need to reset the global parameters.  i'll dig out the link to how you do that and post it in a min (I always forget which way you press the button to do that) :-)

Hope this helps
