getting this error now
CCTVUtilities - Failed to compile: CCTVUtilities.cs(1137,65): error CS1501: No overload for method `Add' takes `2' arguments

Any news on this error yet ?

Same issue. 

I (hope) I solved this, I have yet to test it but i magaged to get CCTVutil to compile by removing the second arg ", item.net.ID" and "key" in "if (!cs.controlBookmarks.ContainsKey(item.rcIdentifier))
as i was typing this i realized this may not be a fix but rather adding the arg ",item.net.ID" in every if(!cs...   in every "add" case its currently 3 am so im trying this tomorrow but what i have so far is going from

if (!cs.controlBookmarks.ContainsKey(item.rcIdentifier))
{
cs.controlBookmarks.Add(item.rcIdentifier, item.net.ID);
}
to

if (!cs.controlBookmarks.Contains(item.rcIdentifier))
{
cs.controlBookmarks.Add(item.rcIdentifier);
}
