I am actually writing my PhD on texniccenter and it was doing fine during the last weeks. Today I really had some problems, mainly caused by a forgotten "]" in a figure-including function.
Several errors showed up, like all the acronyms could not be found anymore etc.
Well, I fixed that and everything seems to go fine. But I saw that TexnicCenter for some reason does not keep the page size (170x240) I defined before, but it directly creates A4 size

In doing so, also the letters increased.
I also tried to update the Miktex packages, and now, I am not able to create the PDF from the DVI any more.
If you need any exact error descriptions or additional information, just ask and I will provide anything necessary. By the way, is there a way to copy (text) from the Toggle Output bar???
Thanks in advance!
