As anyone still using RikReader will have noticed, the current version has "expired". Unfortunately having been over 7000 kilometers away from my PC for the last 3 weeks the next release has been delayed long enough to run into the built in time bomb. Right now I have access to the new build, but not to the correct certificate to sign a Click Once release. I will be back in front of my PC on Friday night and will upload new bits as soon as possible. Until then, my apologies - please send any bug reports or feature requests my way (doug @ this domain).
Update: I've uploaded the new build. Running RikReader twice or using the original install link should trigger the update.
