FeynArts not working properly

I've just uploaded a new version which again should support loading FeynArts, so that FeynCalc and FeynArts can be used from the same session - which I personally find very convenient.

See

http://www.feyncalc.org/download/

and

http://www.feyncalc.org/cgi-bin/diary.pl

FeynArts-3.7 is bundled with the release, so you can simply load FeynCalc with

$LoadPhi = True;
    $LoadFeynArts = True;
<< HighEnergyPhysics`FeynCalc`;

The first time you do this, FeynArts will be patched to avoid name clashes etc. After that you can in principle load FeynCalc+FeynArts without loading PHI, but then you should manually do

SetOptions[FourVector, FeynCalcInternal -> False];

before

InitializeModel[SM]

Otherwise FeynArts will complain and not load correctly

because of

FourVector /: -FourVector[mom_, mu___] := FourVector[Expand[-mom], mu]

in "Lorentz.gen".
