Faman,
you should install the Team Fusion Patches. There is so much more than multiplayer servers and minor cockpit fixes. Just read trough the readmes of the patches. Playing without the patches is really.... not good...
As for the take-off: Yes, it is difficult. But Cliffs of Dover is not alone here. In almost all other sims it is hard to start tail-draggers as well. So, it`s just the way it is and you have to practice over and over again. After a couple of hours, you will get it and starting won`t be a problem anymore.
If nothing helps, you can reduce the realism-settings, but I don`t recommend that. Cliffs of Dover shines when it is most difficult...
As for that I can really recommend getting on the ATAG-Teamspeak and ask for a flight lesson. There will be people around you who will show you how to do everything.
Cliffs of Dover isn`t easy, but you can learn it! And you do that the fastest way with other peoples!
ATAG is here by the way:
