There are several protocol folders showing errors in the logs for protocol not found e.g.

SLDataMiner.txt|SLDataMiner|2992|5248|CDataMiner::LoadProtocol|ERR|0|Directory found for protocol Apache Cassandra Cluster Monitor with version Help but no protocol file found in path C:\Skyline DataMiner\Protocols\Apache Cassandra Cluster Monitor\Help\Protocol.xml

I'm assuming this is a change moving away from having the help files locally, so the folder isn't expected to exist anymore; this does however give the same error with the Functions folder when using SRM aswel.
