Local Man, welcome at CFC !

Thank you very much for reporting the full problem about the CCM 3 download. When answering Keli, I only started a download of the CCM 3 files. After your post I made a complete download and ran into exactly the problem you have reported when trying to extract the files. The only difference to your experience was, that the download was not "sitting" for a good amount of time. The complete download up to the 2,8 GB lasted only 5 minutes.
At present I can only guess what is triggering that problem. I uploaded the CCM 3 files by using a version of sevenzip in the internet. Now I have a new pc with win11 and a different form of sevenzip. May be this is causing the problem, if we try to extract the files with a form of sevenzip attached to win11 ? I had a look into my pms with moderators concerning the CCM 3 upload in the past: The upload was reduced by 7z to 2,968 GB using maximum quality (the second highest level).
At present I cannot do a complete upload of CCM 3 as I am deeply in the modding of the next update of CCM3, also covering most of the additional files for the next version of RARR and the files for reloding AOI (without the music), Hinge of Fate, SOE, WW2 Global Gold and CCR.
I will try a second download and extracting the files by my old win10 pc and the version of sevenzip I used for the upload in the next days. As I am now aware of the full problem, I hope that I can at least do an upload for CCM3 and RARR until the end of this month.
