Quick question, I installed RM and it gave me some server error message after the install finished processing. I had this same error on my last couple of installs. Now it shows the add-on as installed in the list of add-ons, but I can't find it anywhere or in the Options.
You're Product Manager looks really nice. That might suit my needs more than RM. I'll ask some questions on that forum section. If I chose to purchase that add-on, is there a way to get a refund for RM? It might be a better choice for me, but I'd want to look at it closer first.
It'll probably be better if you create a post in the Resource Manager Support/Troubleshooting forum detailing what errors are happening after installing. You may also wish to try and uninstall and reinstall the add-on.
