You're on Windows right? Or Linux? Gonna test an updated repo right now, in case anything is broken
Indeed, I'm getting the same errors, which are new, so it won't be but a short while before Spark sees it, no worries =)
If you want, you can check your revision number, and check out one step earlier, but it probably won't take long to get this issue fixed. These are rare and when they turn up, it's usually just a day or so.
Welcome to the engine and the community, if you like chat, we have a room setup that you can find from the home page. You are welcome to get involved, we need more hands on the core, and we like helping each other as well. =)
edit: Yes, we are able to reproduce this on all of our Windows, and our Linux users are fine, so currently, we assume we just need a new windows build built
But there may be more. Should be ready in no time, since the other platform is fine =)
