Hi everyone!
Basically I've been fixing up my MTB with new parts. I've added a Shimano FD-M591 and RD-M591 to the front and back Derailleurs, respectively. I've also changed the chainset to a Shimano Tourney M151 (48/38/28T).
My issue is that the inner side of the front Derailleur is way larger than that of the outer side, so if I mount it as per Alex's tutorial on the main site - the inner cage smashes into the middle chainring when trying to change up!
If I mount it higher, the chain is no longer central to the grooves of the cage and rubs like hell in virtually all gears.
Am I looking at replacing the crankset?
Here's a couple of images of the problem...
This one shows the inner side of the cage, it's just clearing the middle chainring....

However if you look at this pic, note how high I've had to mount it to get it to do that....
