Hello!

I've been working with AMDIS 2012 to interpret GC-MS spectra from serum and urine samples based on the NIST and MPW library and is has been working quite well for me. Due to some software problems, all the important software was reinstalled. Now AMDIS can't properly identify peaks anymore, even in old chromatogramms from before the servicing. Depending on the library I use, some rare peaks are identified, like the internal standards, but most of what AMDIS should usually find is not found anymore. Instead it identifies a lot of obviously wrong targets. So I know that my library is working, since some peaks are identified correctly, and I know that I set up all of the options as they used to be (Like deconvolution options, etc.). Since I use Retention Indeces, I tried to calibrate with alkanes, which worked just fine. But even the most simple chromatogramms are not identified correctly.
Did any of you ever have a similar problem?
Do you have any idea what might cause this problem?

Thank you for your help!
