I've created previously an application using Logo Soft Comfort Demo V8.4.0.

Now that I've purchased and installed the full version (8.3.1), I cannot open the application created on the full version, as it gives an error:

"xxx.lsc is not a FBD diagram, please check it.".

I'm not able to export nor save in another format the application on the demo version, and I can't find out why the full version is not opening it.

Any experience with this? Thanks!

Hi my friend,

My tip for you is; as you already bought version 8.3, please download an update for 8.4 for free and test it again.

Thanks for the quick reply Padre! I'll give it a try and will let you know.

Problem solved by updating Logo Comfort to V8.4.

Thanks a lot!
