Sorry for the trouble - we used to get a lot of spam on the forum and it was very time consuming to clean up, so we installed some software to auto-detect and remove spam. However it is not perfect and occasionally blocks real users. We just need to whitelist you so it doesn't happen again.
Please be patient about email, we are a very small company (2 people) and we're very busy and get a lot of email! Please allow 2-3 days to make sure we get to it.
