Also, make sure to have the latest version of Universal Email and Site Import. What version of UE and SI do you currently have and what version of DW are you using?
Thanks - I'll have a look. I've just read through the link you indicated. Where it states:
'You can rename (or Delete) the configuration folder to have Dreamweaver recreate it. This will have the effect of disabling all of the installed extensions. You will need to use Extension Manager to completely remove all of the existing extensions after removing the configuration folder. If you do not do this step you will be left with a recreation of the old configuration and possible leaving any corruption intact. This will give you a clean new configuration folder and should get rid of any corruption that may have occurred in there.'
Does this mean I reinstall every WA extension (I've got quite a lot)? And, does it mean I have to reinstall every extension in there? I've got around 100 in total from various software companies. Obviously, I don't want to have to uninstall and reinstall every extension.
