I had that problem with Beck as well. Had to go and re-download. Beck comes in two parts and I had installed only part 1. The big problem I have seen with the Pro Bundle is that they don't tell you that you have to get the base separately. Since it's free, no biggie, I just added to my cart and downloaded. But it was not clear to me that the Base was not in the Pro Bundle. So now, finally, M4 is in my Runtime and working fairly normally. It's Texture Converter and the two plugins for M3 and M4 that's giving me an error.
