Most probably this is a permissions problem.  Mount the partition
which you encrypted with cryptsetup and do a

ls -ld /path/to/mountpoint

there you will see the owner (probably root) and the permissions
set for this mount point.

If this is the case you may change the owner like this:

sudo chown -R youruserid:youruserid  /path/to/mountpoint


HTH, Gregor
