I am doing a complete reinstall, mods and tools, of Skyrim SSE using MO2. Everything had gone smoothly until I tried to use Merge Plugins. If I click the gear icon and make changes to any of the first three tabs i am able to click on the OK button to save the changes. If I make changes to the fourth tab, the Integrations tab, the OK button is grayed out and I can not save my changes. Without the integrations information Merge Plugins won't work.
The Merge Plugins server has been down for at least 24 hours so I cannot reregister. I don't know if this has a bearing on the problem or not.
The error log shows the mods being loaded without a problem. Then there are two messages saying that the program could not connect to the server, after that nothing. I have also tried starting Merge Plugins with the -offline argument and that did not solve the problem.
Any advice would be appreciated.
