I also believe it's ssl downloads of large files breaking the download. But does the download has to be SSL? 64bit version of the release manager would be truly great. But is it possible to make it use the swap file? Also I have run into a few applications with problems addressing more than 4gb even to the swap files. This I had to use an external program to actually edit/hack the application to make it possible to address larger than 4gb in the swap file. Sony Vegas Studio was one of them. Anyway just trying to give you ideas on where the problem might be. Is the 64 bit version far away? Just asking so I can plan for running closed beta with or without a real launcher. Also for other people Reading this thread. This is a beta (test version) Product, and all these errors we find don't mean it's a bad Product. I have full faith in Release Manager and it's capability when the final version is out.
