Material nodes lack inputs and outputs

wow that is odd, maybe you should check your HDD for errors as old harddrives (or even new ones) can garble your data causing errors in system files, not saying its the reason, but you could find your hdd is starting to go bad. Althought if it was on 2 different computers, what may be the issue is your PC, or possible even ISP (virgin media) may have currpted your download half way through or something, try download it again.

How have you addet the nodes? A reinstall will help you ;D

Both right click menu and choosing from the list on the right lead to the same issue. I guess reinstall it is. I hope I it wont happen again...

Existing nodes work fine, but when I try to add new ones they appear without inputs or outputs. This also happened on two different computers independently.
