If you are having trouble with Classic 3.1.0 or Pro 4.0.4 please download and try out the newest version. If these pre-release version solve all the problems then we'll make them official and release them publicly.
Here are the temporary links for the pre-release versions. These links will only be active for about a week, so try the software now, while you have a chance.
This downloads the plug-in only. Remove the old plug-in and replace it with this new one. Back up any projects you are working on. We expect that you will have no trouble with this new software but you never know what is going to happen on someone else's computer.
