OT but I need help please.
My tools in Calibre stopped working after latest download [2.8]. I tried going back to earlier version but it won't let me convert or anything, it keeps giving me DRM error. count pages stopped working too. I don't know what to do.



I just wanted to download my new books and read after a very horrible day. Any nice help would be appreciated.
ETA I think I'm just going to try to leave it until tomorrow. But if someone has an easy fix I'd really appreciate it.
