About the blue cube, any indication of what you did in order to appear? Or it is there from the begining?
The bug on the point #1 is alredy fixed, and the patch should be released soon.I don't think the launcher needs too much resources and that it's causing you lag, it is more probable than RelicDownloader is the problem. But if you want to get rid of the launcher, you can read the topic "How to create an Eastern Front shorcut" stickied in this section.About the blue cube, any indication of what you did in order to appear?

[...]Close RelicDownloader.exe when starting Eastern Front, it could help to prevent crashes!!If you have Retail CoH, you can go to Company of Heroes\RelicDownloader and rename RelicDownloader.exe to RelicDownloader.exe.bak (or whatever you want). If you have Steam version, you need to configure CoH to avoid checking for updates automatically otherwise will be creating RelicDownloader everytime you start CoH.If you are unable to delete that file for any reason, you can just close it after starting CoH in the system tray section(right click over the program and select close, then confirm when prompted).[...]
