Last week I was happily using PI SMT sp1 (not the addin) and this week I loaded PI ACE. Now when I start PI SMT it starts, loads a few programs and just sits on my task bar but no windows come up. I have deleted / restarted computer and reinstalled to no glory. and ideas? I do have the excel addin but from time to time (like now) I prefer the SMT program over the addin.
