Filling out PDF forms

[Lisa Berryhill]

I'm filling out a worksheet I've filled out hundreds of times before but now I get the

message "This PDF document contains forms. The filling of form fields is not supported."

I'm not sure what I did. Any ideas how to fix this?  I know I had previously downloaded

CutePDF to fill out another worksheet. Don't know if that has something to do with it.

Thanks
