8310 PDF Reading - Not Solved

Question

Contrary to what my ham-fisted fingers hit (the Solved Button), I still can't read PDF files.   I am unable to read PDF files unless they are sent as actual email as attachments.  I intend to use the 8310 to read service manuals instead of my computer & some of the files are too large to email cost effectivly..  The prompt I get is "Unable to display file".  Any help is very much appreciated. 

Answer 1

I finally found out how to solve this issue.
For some reason, I cannot use special characters or blank lines anymore in the configuration file.
So here is my new configuration file that works:
# hjkl -> ctsr
map t scroll down
map s scroll up
map c scroll left
map r scroll right
# JK -> TS
map T navigate next
map S navigate previous
# r -> p
map p rotate rotate-cw
# R -> u
map u reload
# b <-> a car le a est plus accessible
map b adjust_window best-fit
map a adjust_window width
# Mode Index
map [index] t navigate_index down
map [index] s navigate_index up
map [index] r navigate_index expand
map [index] c navigate_index collapse
map [index] R navigate_index expand-all
map [index] C navigate_index collapse-all
