Mesh Distortion When Importing Obj In Max

I just noticed this two days ago. All of a sudden Max started to mess up a simple task such as OBJ import in a way that it distort a model (everything that has curves) when importing it back in. For example, if you export a model as an obj file, unwrap it and than send it again, you won't have a clean mesh as you had prior to an export, yet it shows up clean in all other applications so it must be a MAX problem. If you import or GoZ a model from ZBrush - same thing! All my settings are same as before and I do this operations on a daily basis (hundreds of times in my workflow) so I'm pretty stunned to see it all of a sudden. Whats more interesting, the same problem appeared on my job yesterday (different computer, same version of MAX: 2012). I was curious to check it on my home computer today and its the same! All hotfixes and service packs are up to date!
Not interested in FBX, I work with UV Layout and ZBrush.

If you have a solution, I am very interested to know, thx a bunch!

Here are some images:

Here is a same Sphere.obj file loaded in UV Layout.
To repeat my self, none of the import settings in MAX were changed prior to any action described in this post.

Sorry to close this thread so soon, but I figured out the problem.
In Europe we use "," as a decimal key, not a "."
Plus, when you use Num pad You get to use it (,) with more ease in your everyday values insertion.

I changed this several days ago (2-3) in Windows Region & Language settings (under Advanced settings), as I used it before Windows 7. Don't do this!!! Never. It messes up your MAX interpretation of the vertices values. They're there, but not where you put it! It wont work even if you put "." as your Groups seperator. Don't make the same mistake I did. Keep things uniform.

I was so shocked to see the error this causes that I almost fainted
