Hi Bought Reaper a few days back, But I am Constantly getting issues about every few mins making it impossible to use Reaper, all i have is this Windows vista 64x Crash log pointing at an issue with CK_WAVESHAPER.SEM, Not sure what this is,but i do no i have no such plugin running in my project if it is a plugin. when Reaper fails, it still plays audio and maybe the odd midi track, but most midi stops sounding, hence i have to Restart Reaper,It just seem to happen when i am moving data around that is all i can add. I know this Windows log will not really be of use, but i will post it just to show the error log, thanks.
