Error when clicking add config

Ahh ok, I updated to the dev version and that error does go away, but when I go into Site Building > Media Movie, on any of the tabs I get this error message:

user warning: Table 'droop.media_mover_step_map' doesn't exist query: SELECT * FROM media_mover_step_map WHERE cid = '' ORDER BY step_order in C:\wamp\www\_arms\sites\all\modules\media_mover\class_media_mover_configuration.php on line 235.

I did run update.php, but it didn't look like anything was updated.

You are right, I was using version 2 dev. I removed it and installed dev 1, but now I am getting another error when I go to add config again. Same error as the first, but different table.
Fatal error: Call to undefined function ffmpeg_wrapper_frame_sizes() in C:\wamp\www\_arms\sites\all\modules\media_mover\contrib\mm_ffmpeg\mm_ffmpeg.module on line 369

Would it make sense to install both stable releases of ffmpeg wrapper and media mover? Sounds like that could eliminate these errors.

Well I ended up installing both of the "stable" releases of ffmpeg wrapper and media mover and the error went away. I built my config file succesffully.

I hit "run" to run the config and I got these errors:

It made all the folders but they were empty.

I am sure it's something I am doing. What should I do from this point?

Is it failing on making the thumbs or locating the FLVs? I am referencing a CCK field called videos which is a File Field. The files are of type FLV
