i reinstalled it and skipped doing 4.08

That's why it CTD's at 5%.
Both HSFX and UltraPack require a vanilla clean 4.09m installation, which is:

1.) Install IL-2 1946
2.) Install Patch 4.08m
3.) Install Patch 4.09m

The next steps for HSFX would be:
...
4.) Install HSFX 4.0
5.) Install HSFX 4.1

The next steps for UltraPack would be:
...
4.) Install UP 1.8
5.) Install UP 2.0 Update
or, alternatively:
...
4.) Install UP 2.0 full package

In either case you need to apply both patch 4.08m and 4.09m to get to the starting point of the modding packs.
