Pentaxuser - can't remember where I ordered the chemistry, but I get pretty much all my stuff from one of either Calumet (www.calumetphoto.co.uk), Firstcall (www.firstcallphotographic.co.uk) or Silverprint (www.silverprint.co.uk). Calumet can be rather arsey about shipping chemicals though (normally charging some kind of hazardous substances shipping premium that nobody else does,) so Firstcall or Silverprint are usually my first choice.

I'm afraid I can't help much with the rotating documents problem - I think you need a Windows expert! If you can open them as-they-are though, maybe you could try printing them out to read?
