I want Pro Version

hey there,
I started messing around with this plugin but figured i’d uninstall it once I got the pro-version. While playing around with it the french side of my website broke. The menu had items on it that weren’t supposed to be there and the drop downs were added to the header making it a stacked menu – I deactivated it and deleted it (which fixed the problem) – I then realized there was a feature I wanted to double check on I reinstalled it and the menu was as broken as I left it. I tried using the revert setting feature but it wouldn’t help. The french part of my website is totally broken with the plugin installed.
I want to buy the proversion I just dont want the setting to still be locked in the messed up form. Is there a better way of clearing the setting or is there something I’ve done thats locked that in place? Just to be clear – deleting the plugin reverted my menu to normal.
