I am doing some pretty basic cartography stuff using my college's license for ArcMap 10.0. and I recently had to reinstall it due to computer issues.
I reloaded some maps I was working on and all my X,Y data symbols have changed to #, %, ^ or something similar instead of the usual circles, stars and stuff.
When I look into the symbol selector, specifically the ESRI style references, I can see the names of the symbol i.e. what they are supposed to be but instead I get letters or signs overlapping like a black % sign over a green capital G.
For example, the Circle 1 Default marker is replaced by an exclamation point.
