Thanks for reply ACDC, I am now at the point of no password at all for MySQL and have no problem using it to access non-Aware databases within the root.
From the error, it seems Aware will always look for BASDB in the root C:/MySQL/Data and I note that settings in the Aware props/options files do not actually specify (or allow) a root directory change.
Support - if there are any logs or something I can send/tell you about, let me know as I think this is a really useful thing for others who might be dealing with HUGE databases and want it on a dedicated drive - my client creates 160 records per day on an existing db of 43,000 records!
