As for the log entry there is something interesting that wasn't there before which is the I3D ver. 2. There is one thing about this that really doesn't make much sence, a friend of mine who plays IL-2 had this exact problem happen a few months earlyer. What is bizzare about both cases is the fact that 1. the sound mod was working the day before. 2. Nothing realated to UV3, the conf.ini, or anything about the game or the sound setup had been changed and both of us have UV3 working in UP3.
