Help, RouterOs v5.14 on RB1000 Power PC cannot save backup.

Greetings,
I have Router Board 1000 with Os v5.14. I have a problem to save backup configuration.
This is a message that I get:

[camouflage@mikrotik] > system backup save name=26july2012
Saving system configuration
Failed to save system configuration backup
action timed out - try again, if error continues contact MikroTik support and send a supout file (13)

I have checked with /system check-installation and the result is done.
The license too.
And I try everything that I know, but doesn’t work.
Anybody can help me? to resolve this problem.
Every comment I appreciate. Thanks before.

Done.
I reupload packages, and reboot the router.
All work perfectly!!!
Hope this help another.
