B3 - Video creating - Error if sound file doesn't exist

[Dreamer]

If the file in the Play sound field doesn't exist (it has been moved, for example), just a strange error is shown while creating video:

Exception EMon in module libmcl-5.3.1b4.dll at 000648F3.UNI protocol fault.

It was pretty hard to find where is the problem, even for me, I thought it's the video format / codec issue, so if the sound file doesn't exist, another - clearer error message should be used, if possible.

When creating "EXE" slide show, no error message is shown at all.
