Thank you for being fine with all my questions, I do have a lot. So I
followed the purge command and got rid of files. Then I also used the sudo
chown command to fix that permission problem. I had to use it again to make
install and I was then able to make install. So I had to recreate my
flowgraph and run it. It is not working but it is a different error now.
Here it is:
Traceback (most recent call last):

I have my block, Chunks to Symbols, set up like this:

it seems that the imaginary numbers are represented as 'j's instead of 'i's
so I used 'j's was that correct or may I be missing a factor to make it
work?
