I downloaded the Sibelius 5 demo some time ago and was initially able to use it successfully. However, at some point it stopped being able to even open. After a couple days of debugging and searching I found the Google Desktop issue and thought I had things solved. A little while later, however, it started hanging during startup with the displayed text "Creating tool windows: Ideas detailed view".
I tried many different things to get it to work, including various Microsoft .NET Framework patches. I had pretty much given up on it for a while and resigned myself to the fact that I would have to do a project due in January in Finale 2007 (an equally capable program, but missing a couple features I had looked forward to in Sibelius 5). However, when I heard talk of other people having issues with the Ideas View and that some of them had been addressed in the 5.1 update, I downloaded the 5.1 demo. Unfortunately, I still had the exact same error.
Does anyone have any ideas on this? I would really hate to make a decision about what package to buy on the basis of this issue. I am running Windows XP (32-bit) SP 2 on a 3.2GHz Pentium 4 with 2GB of RAM and my soundcard is an M-Audio Audiophile 2496.
