I normally don't have a problem with this kind of stuff untill now. I will be posting a picture of a ship I have built in the album gallery shortly after posting this. I had built a bryce model of this ship. In total the ship has about 22 MBs of information and I have never had a problem till this day. I was finishing up on this ship buy putting the last assembly of models to some Bio Domes I had built on the ship. I was able to save the ship itself, but when I brought it up and put another model including trees a lake and ground with a platform to hold it, the model itself was finshed and ready to be saved again as a new model from the add on. I save it to the holding area of bryce and it seemed like all was going well and then I attempted to save it out of bryce and then the shock of an error from either bryce or Windows XP had popped up telling me that we are sorry for the inconveince and the software was shutting down and the data would probubly be lost. Also it wanted to send over the internet which the PC is not hooked up to, a message of the state bryce was in when bryce had the problem. What is funny is that when this gets this way it won't delete the models built before it. It just leaves a white box where it was. If any of you have heard of this and know of a fix either from DAZ or Microsoft please let me know. I have never seen this before and am bummed out of all the time it took to build this. About 32 hours. Thank you for helping.
