I've taken a read through the thread, but wasn't able to see anything that stood out as being the same issue I have here.
I installed the Six Updater suite from the site earlier, however when I start it up - anything I mouse over turns into black boxes.
I've tried uninstalling and re-installing, with no success - I also re-installed my .NET framework too

Apologies if this has already been posted, but I did read through and didn't spot it. :/
