The texture pack I'm currently using is exactly the same aviabile for manual download (77 files, 1 folder; 97,8 MB (102.560.394 byte)). Anyhow I overwrited it but it's still the same. I don't think it's a strictly taxture problem, it's like the position of all KSC is wrong or the terrain altimetry is messed up because when i try to take off from the runway i can clearly see the the runway itself is about 10m-15m from the surface of the water.
