Would help to know which module is causing it. Does Win10 really have the title font THAT small?

You could check for it by disabling all the modules, then re-enabling them one by one to see which one(s) cause the error.

Though I have a gut feeling that it's an xModule with a LS build newer than 2009. Those don't play well together, and I vaguely remember that it gives that error when you try to load 'em. Alternatively you might be trying to load a 32bit module in 64bit LS or vice versa, though I can't remember what exact error that gives you.
