Long story...I'm currently using 1.4.9
I upgraded to 1.5.x (whatever the current version is) beginning of January
Lost my products, front office, back office, etc.
Tried to down grade back to 1.4.9. still unable to get products
So I fresh installed 1.4.9 - finally got it to reconnect to my old database, got categories back, attributes, etc. but no products and no pics.
