I am having some trouble with TraceIt.
It was working fine as always, but don´t know why? from two weeks ago It quit working.
We are working under Windows 7 64b
Have there been any changes to the computer you are running this on? For a simple resolution test, I would try a system restore of Windows to just before you remember the issue starting just incase it is a conflict that Windows might have created with an update.
Otherwise I will forward the error you are getting to someone wiser than I am for review.
