Need to change block location

Hi,

I need the carousel to show up in a different block than the default as I do not have this region in my theme. I have tried replacing 'content' in the jcarousel_block.module code with 'content_top' (the location I need) but have had no luck and still get same error msg:

The block jcarousel block was assigned to the invalid region content and has been disabled.

Do you know where I should be changing this?

Also, I need to be able to choose the orientation of the carousel as well. Is there a way to set it to horizontal?

Thanks for any help. I greatly appreciate the effort of making jcarousel user friendly!
