For the users on Vista and Mac that are having problems with importing videos and/or getting stuck at 80% complete creating workout videos, please try the method(s) outlined below. We have been able to fix the problems with Vista and High Reps chapters 4 & 19, videos not importing, and other errors by doing this. We have submitted all of the information that you have provided to us to our developers and these problems should be addressed and solved in the next version of the Workout Blender, so you also have the option of waiting if you do not want to reset the program as cautioned below. WARNING Please note that you will have to re-import your videos and re-create your workouts since this resets your Workout Blender. If you have workout videos successfully created already, you can easily save your "premix" workout videos themselves by dragging them out of your Workout Blender Videos folder and into iTunes or any other folder on your computer BEFORE starting this process. You will not be able to edit these existing workout videos, however, unless you re-create them like you did originally using the Blender. WINDOWS 1. Exit the Workout Blender, then open your Control Panels and choose "View by: Small Icons" in the upper right corner. 2. Click to open "Folder Options" 3. Click on the "View" tab at the top of the Folder Options window that opens. 4. Under "Hidden files and folders" in the list of Advanced Settings that appears, click on "Show hidden files, folders, and drives", then click "Apply" at the bottom of the window. 5. Leave the window open since you will need to reverse this process in a minute. 6. Navigate to the folder: "Your Hard Drive" > Users > "Your User Name" > AppData > Roaming and drag the folder "Cathe" into the Recycle Bin and you can close all the folders you opened. 7. Go back to the "Folder Options" window and check "Don't show hidden files, folders, or drives", click "Apply" and close the window. You can also close your Control Panels. 8. Restart your computer, then when it is done restarting launch Workout Blender and attempt to import and/or create a new video. MAC 1. Exit the Workout Blender. 2a. If you are in a version of Mac OS X that is prior to Lion, navigate to the folder: "Your Hard Drive" > Users > "Your User Name" > Library > Preferences > cathe 2b. If you are in Lion or Mountain Lion, step 2 is a bit more involved. Apple decided to hide the Library folder in these versions of OS X, so you will need to do a bit of old-fashioned command line programming. Go to your Utilities folder inside your Applications folder and launch Terminal. Once the grey block cursor appears (it will be after your user name and $), carefully type chflags nohidden ~/Library/ and hit return. Quit out of Terminal and you should now be able to navigate here: "Your Hard Drive" > Users > "Your User Name" > Library > Preferences > cathe (NB - if you would like to make the folder invisible again, in Terminal type chflags hidden ~/Library/ ) 3. Drag the folder "cathe" into the Trash and you can close all the folders you opened. 4. Restart your computer, then when it is done restarting launch Workout Blender and attempt to import and/or create a new video.
