wrong timepoints for extracted data in spectra

Question

Hi,
we are using Chemstation to reprocess our LC-MS Data. We installed the software (in offline mode) on win10 and our computer for measurement is using Win7. We now got the problme that we cannot extrat the masses in the MS-spectrum. Because the timepoint for the selected peak is wrong. e.g.: When we chose "select spectrum at any time position" and click at 0.796 min in our spectra the shown report got the data for time = 2.519. It is quite randomly which timepoint in the spectra is set for the extracted data.

Does anyone know this problem and have a solution for it?

Thank you and best regards

Hi PLI , 
 Could you please verify that both computers are using the period '.' as the decimal separator, and not a comma, ','? It is difficult to tell, but it appears that the time given in the spectrum window is listed as 2,519 and not 2.519. Current versions of ChemStation will not run if the decimal separator is not set to be a period, but it is possible older versions may attempt to run in that configuration, but I'm not certain if that was ever a supported configuration. 
 The setting can be found in the Region section of the Control Panel under Additional settings... 
 
 If that doesn't appear to be the issue, could you please provide revision information for both version? This can be found in the Help->About menu.
