Can''t send a file to another user!

Wildfire : 2.4.4

Spark : (Today upgraded from 1.3.x)

After spark upgrading from 1.3.x, I tried to send a file to another friend

my friend’'s client is pandion2.5

but I got this message

“You were unable to send the file to XXX”

File type was Excel file…

Both program Pandion and Spark can’'t transfer file to each other???

what’'s the problem???


Can you find any error messages in the log files for Spark in the logs directory?

Also anything on Wildfire logs?
