4.11 General debugging

[Sledgehammer427]

First post on the site, having trouble with the patch.

My game does not seem to want to upgrade from Version 4.10.1m,

Perhaps this is because the files I have are broken or something like that, either way, heres the files and where I got them. I have IL-2 1946 boxed copy with the bonus DVD. I don't know the version it starts at or which version I have, that is if English and International are different.

From my base install I go

-4.09m from Mission4today, a 500mb plus zipped file with an .exe named 4.09m
then
-IL-2_MegaPatch4.10.1m_EN, from mission4today. 1GB plus file with an exe named RunMe
then
-4.11 downloaded from mission4today using the megaupload mirror
and
-4.11.1 using this site.

Have tried multiple approaches, run as administrator, basically everything.
Running Win7 Home Premium 64bit

Hope I've provided enough info!
Thanks!
