Hmm, have you used the selfextract - or noselfextract- Version?
Perhaps you have installed something wrong?
Please look under NW2- Campaigns- SoDCampaign, if there is a module.jrl file, and how much KB it has.
Best, you make a screenshot from your SoDCampaign- content.
It is a very old module, and I`m not doing NWN2 for a long time
. If you have not installes the campaign correct, you can try this again. If all is correct, only the module.jrl is missing, I can send you the file and hope, this will help.
