I did clean install 1.3.7, no data, no other add ons.
Run SQL patch
copied all files (admin folder and extra folder)

[FONT=Arial]I even run 2nd time the SQL patch, still the above error. This is my 3rd try on 3rd store, perhaps if I sleep on it I will wake up with a miracle revelation which will point me in a right direction. What's depressing that I was able to install it without any trouble the first time I tried it (mind you that was on ISP), these tries are on my laptop, I wonder could that be a problem??
