As is often the case, sometimes addons can cause a ton of trouble. I am not saying curse did it but add-ons are not supported by RoM. We can try and help but my suggestion is to uninstall CURSE CLIENT and remove all folders and any trace of the words in your folders that relate to curse and add-ons. reboot. and add that one first. No promises. If it were me, I would remove it and let sleeping dogs lie.
Or uninstall it the day before server reset and and all files will be pristene and then install it first and go from there.
