I have created rrd files successfully to do different things in the past. This is the first time I've tried it on a Windows 10 machine. I'm not sure if that is the issue though.. I am having trouble getting any RRD file to run successfully on this machine. It usually times out saying it can't connect to the database. What is weird is if I just double-click an rpt file, Logicity has no problem running the report. But if then I create the simplest of Solutions that just does all of the defaults like connect to the database and ask for parameters, and view the report, it won't run.
