I formerly laptop broke down, I got a new one on which I installed TexnicCenter and MIkTex to compile my latex stuff. Fortunately I could save all the Latex OUTPUT directory on my memory stick before my old laptop died out. I have been running my 1.st laptop latex files on my new computer.
I tried to modify the file, compile it but....THE SOFTWARE DOES NOT OUTPUT ANYTHING.

"Pdflatex invalid argument" and It complaints about the lack of the .aux file while the aux file is actually present in the folder where the .tex file is located.
Should I re-install the whole software or can I adjust it and fix this problem?
Thanks
regards
Marco
