Hi!

You just need to change "acroview" in the following line to "acroviewR10" or "acroviewA10":

// DDE: Required for Adobe 8!
DDEOpen('%$("AcroRead")',"acroview","control",0);

If it does not work, then probably you are using Acrobat 11 or another version. Thus, just change "10" to "11" and it ...
