Thanks for your response.
I have looked to delete the cache file again but it doesn't exist. I'm operating on Win 7 (64bit) with an intel i7 2.93GHz processor and 6GB of RAM.
I'm using a local testing server running on XAMPP with MySQL 5.
I'm using one of the eCommerce databases supplied by WebAssist,I've posted the .sql set-up file as a text document.
DAssist goes through the whole process without problem until the Finish button is pressed, at which point it crashes dreamweaver.
