When selecting a list that has available numbers, the Campaign rejects it.
This usually happens with smaller list and is a indication that the available counter needs to be reset with Listmaker Pro. To do this: 1. Open Listmaker Pro and open the list in question. 2. Go to Utilities/Rework List and do not check any dispositions. 3. Hit Rework and it will show you how many available records there are. 4. Now you should be able to load the list into a campaign.
