I had 1.45 installed and running fine with my e815. I just downloaded 1.6 and i'm getting the "Application has generated an exception" error. What was added to 1.6 to make this error appear. Happens on all 3 of my computers which all have xp sp2 pro, .net 1.1 and all updates. I was so excited to hear that the 815 can do SMS but i cant even try it now :(
