Hi,
After the last update I'm receiving the following message log when selecting (most) datasets and can't update or use them.

Hmmm, it happens when selecting from the tree or the data manager?
Both.
Data manager I got it first, so thought maybe when selecting it with the Strategy monitor it would work but got it there also.

Although I haven't been able to duplicate this, I added some defensive code to attempt to resolve it for you for Build 124.
I'm getting the following message regarding the error when updating individual symbols using WealthData.
Maybe it gives some more information for you.
