Hi Yddona, sorry for the late reply.
I don't have many ideas on this one as I am not familiar with power builder. The main thing I would check, which was my issue, is if all services are being able to be ran.
I don't know your environment, but in our system, we use AD, so we had to create a service account in AD, and give permissions to all log folders. This is what worked for us.
I hope it helps.
