Autostakkert 3 Can’t Open AVI file Help !!

[Startrek]

Help , need some advice from Planetary folk out there !!!
Spent an hour or two successfully processing some lunar vistas using Autostakkert 3 and then Registax 6 ( been using them for years without a problem )
Tried to load my 4th image ( 1200 frame AVI file ) , pressed Open and saw the following error message -

Failed opening file C: ..................... frame count:0 fourCC Check limit. The start frame (691) is greater than it equal to number of frames in file (1200)
Photo attached

Rebooted my laptop and tried to Open a few other AVI files , no go , same error

Any ideas what the problem is , never experienced this before
Been using AS and R6 for 4 years now

Thanks

Forgot to mention all my AVI files ( about 22 ) open on my laptop and video runs perfectly

Went on Autostakkert Users group
Emil advised to disable “Limit”
Problem solved !!!!
Had no idea why Limit was set to 691 ?????
Didn’t even go anywhere near the Limit button ( Gremlins )
Back to processing.......
