Included PDF as first page creates empty page before it

Question

For my thesis I have to use a specific first page, which is only available as Word.

I filled it and saved it as PDF and included it with my thesis with

\includepdf[pages=-,templatesize={145mm}{210mm},noautoscale=true,offset=-20 -190]{Frontpage.pdf}

The problem which occurs is that I have an empty first page befor the wanted first page.

On Google I found solutions like How to include PDF pages without a newpage before the first page?

But even with something like "pagecommand={\section{Frontpage}\thispagestyle{empty}}" the only result is, that I have another entry in my table of contents.

How can I make this thing work?

Antoher solution which would work for me would be a Word to LaTeX converter which converts the Word Document as it is. Everthing I found in this direction had problems with positions and graphics of the Word Document.

Edit: I found out, that the problem is because of my used documentclass. For my thesis I use this one:

• Thesis.xls http://pastebin.com/yavTC0mu
• Example: http://pastebin.com/fyRKADmf
• Result: http://files.liebich.co/test_Thesis.pdf

The Result with this looks like this: With documentclass book it is working correct:

Answer 1

The abstract seems to be programmed wrongly:

\newcommand\abstract[1]{
  \btypeout{Zusammenfassung}
  \addtotoc{Zusammenfassung}
  \thispagestyle{plain}
  \begin{center}{\huge{\textit{Zusammenfassung}} \par}\end{center}
  {\normalsize #1}
  \vfil\vfil\null

}
{
  \vfil\vfil\vfil\null
  \cleardoublepage
}

note that the first line says \newcommand not \newenvironment. Thus the

{
  \vfil\vfil\vfil\null
  \cleardoublepage
}

is never picked up, lives on and leaves that stupid blank line.

You will have to change the code in Thesis.cls in order to get rid of this.
