Thanks for this update Jesse!! I bought it in simmarket.com.  
Can i expect it to be available tomorrow there?
 
Thanks!  

Don´t worry Jesse! My simmarket purchase id# with the SU p38 is 558053, but I will wait for it.
Your job on this is already done!!! Thanks!!

I downloaded what I thought was the patch from the site but it seems to be vs3.0.0.3 created 10/3/2009.
I assume that isn't the patch?
Originally purchased from Flight1, where would I get the patch vs?

Yes, it sounds like you have the original file.

3.1 or 3.01 I can't remember which I used in the installer can be found when you run the Flight1 file. When the payment screen comes up you should see the price, product, name and version number on the right side of the screen. The price for the new one will be listed as $20.95. The readme that pops up when you first run the Flight1 File also has the version listed.
 
When you finish the Fligh1 Process and actually begin to install the file it should also be listed in the information section.

Jesse, can you help me on this? Simmarket.com said that their system is updated and the .exe file of the SU p38 is up to date, as they say in here:
-----------------------

But when i download it, has the same size of the old installer (Size: 118.427Kb). And in the install process the message that appears in the window follows:
-----------------------
Legacy of the Sky: P-38 Lightnings X
English Version 3.0 for FSX SP2 or Acceleration
-----------------------
Can you confirm that it´s the old installer?  
 
So, i think that simmarket version is not updated yet, don´t you agree? I oppened a support ticket with then, let´s wait for their answer .....

Jesse,  
The answer from simmakert. com was this:
 
----------------------
Our file is from Sept. 28 and we have not  received any newer version from the developer to date nor any information about an update.
 
best regards

So, i don´t know how i can get this updated version. Can we do what you suggested before? I PM you my purchase data in simmarket.com and you send me a key (If it´s possible of course). Thanks !
 
In time: Thanks boxcar!!!! Your help is much appreciated!
