Hello, Christoph.

I'm guessing that you're running on a Windows 64-bit machine.  We discovered a 
problem after releasing Mathematica Player in which the MathLink libraries 
aren't fully upgraded to version 6 MathLink, leaving them in an inconsistent
state.  We never discovered this because 5.2 and Player works fine if you have 
6.0 installed, and we overlooked the scenario of 5.2+Player on a machine where 
version 6 has never been installed.

Our Tech Support department will be posting an FAQ very soon (sorry, I don't
know the URL yet) with an .msi installer file that completely upgrades MathLink,and we'll replacing the online version of Mathematica Player with a fixed 
version in the next few days.

In the meantime, the very simplest solution (a bit time consuming, but less
confusing and error-prone than any other solution I could give you) is to...

* Completely uninstall Mathematica Player and 5.2.
* Open a command prompt and change into C:\Windows\SysWOW64.
* Run...
dir ml*
* If you see any of the following files, delete them...
ml32i1.dll
ml32i2.dll
ml32i3.dll
mlmap32.mlp
mlshm32.mlp
mltcp32.mlp
mltcpip32.mlp

* Now reinstall 5.2.  You can install Player again once the tech support FAQ is 
available (which another Wolfram person should post...I'm going to be on a planefor the next several hours, which is why I don't have all of the information
handy).

I apologize for the experience.  You can feel free to contact tech support if 
you have any continuing problems.

Sincerely,
