Re: FeynArts and Mathematica 2.2.3 !?

 I forgot to include my name and e-mail when I first sent this message so 
 I'm sending it again with this information.

 Hi:
 I'm the one who first asked about FeynArts and FeynCalc. I finally got
 FeynArts to work with Mathematica 2.2
 I was originally trying to use FeynArts with Mathematica 2.2.3 but it never 
 work and was giving a puzzling error messages. It was just a coincidence to
 run it with Mathematica 2.2 and it worked quit well. I don't know yet 
 what is the problem between FeynArts and Mathematica 2.2.3, however, I'm 
 attaching a sample notebook with the error messages. This notebook runs with 
 Mathematica 2.2 with no problem!
