Hi,
I have Mathematica5.2 (student version) installed. I downloaded the latest version of FeynCalc (fc5beta3.zip). When I try to run it, I get the following error:
   

<< HighEnergyPhysics`fc`
FileNames::strs : String or non-empty list of strings expected at position 2 in FileNames[FeynArts.m,{},3]. More...

FeynArts not found. Please install FeynArts, e.g., in
C:\Documents and Settings\Fadi\Application Data\Mathematica
and reload FeynCalc. FeynArts can be downloaded from www.feynarts.de
------------------------

Then, I downloaded FeynArts-3.4 and when I try to run:
<<HighEnergyPhysics`FeynCalc`
<<FeynArts`FeynArts`
It opens a box with:

An installation of FeynArts has been found in C:\Program Files\Wolfram Research\Mathematica\5.2\AddOns\Applications\FeynArts. This program will now patch FeynArts to allow interpolation with FeynCalc. Continue(yes,no,abort)?
-----------------------

When I type yes, it gives me a long error expression for many symbols e.g. like $ParticleHeads, $FermionHeads, FourVector etc:

$ParticleHeads::shdw: Symbol $ParticleHeads appears in multiple contexts {HighEnergyPhysics`FeynArts`,HighEnergyPhysics`Phi`Objects`}; definitions in context HighEnergyPhysics`FeynArts` may shadow or be shadowed by other definitions.More...

$Failed

-----------------
Please help!!!!!!!
I badly need to work sooner ;(

Cheers,
mariam
