Support Board

Hello good day. Please, lately I get the Message Log that I can't use some of the Studies to Graph things and it tells me that until I remove it The Sierra Chart may be unstable. For example Studies NMinBars. I am using it for years and suddenly it tells me this. Another one I think is VWap Bands. But the most that worries me is that I get the Volume profile that I am using a lot. Twice already the Sierra chart was disconnected for a few hours and I don't know why. I have package 5 and it was always good I have already sent support the message log but I do not understand where and with whom I can communicate. Links come out but I can't find the solution. Can you please help me or give someone who will tell me why they are doing this? And right now he's doing it again. I have released NminiBars but I don't know. Now he logged out again two hours ago and says ... Connection error from servis: Rithmic Trading
