Unable to send finalized form

But hang on, a small line popped up quickly and then disappeared. I had to save the form a few times to be able to get all the text. It says "Invalid RSA public key. Form has not been saved as finalized."

I looked this up on the forum and found someone else had the problem and it looks like it has to do with my encryption key. Cannot Finalize Forms in ODKCollect

I will try and resolve that now.

Thanks,
Melinda
