I powered up Aris Express this morning and went into an existing Data Model. The symbols for the attributes had all changed to white lozenges and there was no way to put any more symbols on the diagram. The problem is the same for all the Data Models, but the other diagram types seem to be OK.
I have noticed the last couple of times I have gone into Aris Express, it has asked me if it can access the internet - it doesn't usually do this.
Have there been some changes to ARIS Express that may have done this? I have attached a screenprint.
