I recall something similar happened to me but I cannot remember what the cause was.
- Try using "dsjob -run -mode NORMAL {proj} {job}" to see if your new job will run
- Create a new project and see if you can create/compile/run jobs. If not, then a full re-install is going to be your quickest path
Then backup the project, delete & re-create it and re-load your jobs. That is faster than trying to figure out what has gone wrong; particularly since fixing that might involve re-creating the project anyway.
