Trends & Archive Data Not Displaying

I have tag logging enabled, I have the OnlineTrendControl on a picture and I am feeding data into the tags using TagSim. The live data is recording fine, but if I close the trend window and re-open, all that data is gone? The TrendControl is linked to the Archive database and the tag selected from the Archive List. It just seems as though the tag logging is not actually doing anything? The connection on the trend is green, with all data sourcesreadingonto the control. TagLogging isticked in startup but I haven't noticed any new database being written for today? There are only two database files in the directory and I have had this enabled for weeks? Looks like Tag Logging is not working? Cheers.

Then I created a new archive folder in Tag Logging console and put my tags in again, and hey presto, the tag data is alive and recording in the trend. Really bizarre but I guess something screwed up during editing.
