You need to enable the log on your file.
On QV Desktop go to Setting-> document properties -> General tab -> on the right, check generate log file.
The log file will be generated during reload and will have the same name that you .qvw has but with the extension .log
It will go to the same folder as your .qvw
Sometimes windows will reconize this is a text file (it is!) and will hide the extension and change the icon to text file icon.
After this we can have more details to help you will the reload problem.
Hope it helps,
