recurring schedule with server groups

I am scheduling a crystal report in a clustered BOE xir2 environemnt on windows.

when I schedule the rpt to run now with a specific server group (for ftp purpose- I run on server A)

this process works fine. but when I want to run at say 1am every day it never takes off. When setting up schedule I have been testing I put down to run in 30 minutes and run every 5 minutes for 1 hour..but nothing !!!

any suggestions
