Eh, i had tried to install HSFX (v 4.1), after reinstall of course, but game looks as a pure version of IL-2 (no new flyables, cloudmods etc.). Could you upload this folder somewhere (w/o mods, just clean Mods folder and it's basic subfolders). Thx in advance.

If you are installing HSFX ... then there should be no mod folder at all. The whole point of HSFX is that every mod is repacked into .sfs file format. This means that there is no mod folder at all. Because the mods are compressed into .sfs files then they load much faster. That is what sets HSFX apart from the other mod packs. UP and UI both have large downloads that go into the mods folder. They also both take several minutes to load ... even on high end computers. HSFX loads the same amount of mods in about the same time as the default game unmodded.

So as far as giving you a mods folder for HSFX ... I cant because it does not exist with that setup. Everything is packed into the HSFX files. If it did not load right after install then either

A - you screwed up the install

B - you have corrupt download and it did not install correctly

I am going to bet you have problem B. try re-downloading the HSFX mod and reinstalling it. Use the tool they offer to verify you don't have a corrupt download.

Edit: Did you just download and install HSFX 4.1 only???

Because it might not work if you did this. You have to install HSFX 4.0, then upgrade to HSFX 4.1.
