Does anybody know what causes this error message. Bryce will now just not open. Uninstalling and re-installing completely has not fixed it! I'm running a PC on WindowsXP and have just installed AOL Broadband. The last other change that might affect Bryce was installing the Greenworks tree sampler from DAZ I've emailed DAZ 2 days ago, but so far no response (so either too busy or they don't know either) many thanks in advance peejay
