Please help! They have updated my computer to Windows 7, and I have tried to reinstall MiKTeX2.9 and TeXnicCenter. When I run a LaTeX program, it tries to install 412 files from CTAN, and I get the error:
pdflatex.exe: A timeout was reached while receiving data from the server
And then I get a LaTeX error that
pgfcore.sty was not found.
Is it some permissions problem with Windows 7? I have administrative privileges that I could use, but I don't seem to be prompted for my password...
This is driving me crazy! Any help is much appreciated.
