I am not clear with problem description. Job is working but files are not getting copied/restore?
1. Go to Loshipping Monitor, Click on the pair and Check Copy/Restore history. Is it successfull?
2. If there is no errors then I believe that everything is working fine.
3. All you need to do is create sample table on primary and check if it ships the table.
4.. If data is getting shipped and Monitor server is showing "increasing delta" then problem boils down to the fact that data is not getting updated in the table. Below arrticle may help
