I keep getting a message saying " I don't have permissions to certain tasks like; saving work to USB memory stick, can't see any document on my USB memory stick
The permissions error can be resolved by performing the task as root user or by changing the permissions. If you can't see anything on the usb it is probably not mounted.
If you don't know how to do this, post back.
I'd agree with MTK358 about getting a more current and better supported distributions.
