App Stopped Workingg After Update but now is fine after this.

1. Choose Go>Go to Folder from the top menu.

2. Input ~/Library, click Go.

3. Delete the IU folder under the path
Containers/com.Wondershare.VideoConverterUltimate/Data/Library/Application Support/Wondershare/VideoConverterUltimate/

hope this works for the rest of you.
Great app though other than recent update.
