Do you remember the XXX and YYY in: "The instruction at "XXX" referenced memory at "YYY". The memory can not be read."? That seems to be quite a frequent error in windows and is not hardware related. The only common thing seems to be programmes using names that are too long for the memory allocated to them. Here are some more things to try... :biggrin: Have you emptied your temp folders? Have you moved them out of the windows folder? In studio, have you got the "check for updates" set to "never"? Have you deleted that "What's new at DAZ" TAB?
