routerconfigs only works the first time manual run

[Arsalan]

I have cacti-0.8.8b with routerconfigs-v0.3-1 installed on CentOS 5.5
When I add a new switch to backup and I run it manually it works great and backs up the switch but it won't run automatically on Schedule or even if I run it again(right after or later) it won't work. All I need to do is to go to router configs and select one of the switches and just make a small change on Description feild and save it and run the backup manualy again and it works. It will change the Description back to old one which was the read name for that switch(with upper case and lower case) but again doesn't run as Schedule. Please help. Thanks.
