Hi Karl,
Thanks so much for taking the time and going through all the steps to set up an account!
I think I've found the problem. It seems that when I added the code to clear the cache, I forgot to go back and add it to the NewItem method as well, which is used during the account creation process. I've created a new build which I'll upload to Snowcovered here in the next few minutes. In the mean time, and I can't be sure about this, but I think you can solve this problem by setting the cache time to 0 for the module you added to the home page to support downloading styles (mid=369). If the cache is already set to 0 for this module, then we have another issue that I'll need to resolve.
Thanks for your patience and for using metaPost!
Don
