DryLab has generated some unexpected intermediate results

Windows 2000 Professional with Service Pack 4
Celeron 700 Mhz Processor and 256 MB RAM

has anyone seen the error below? If so how was it fixed?

DryLab has generated some unexpected intermediate results. Further calculations are impossible. Possible causes include typographical errors in the input data, elution of a peak before the gradient, and improper equilibration between runs. For more information see HELP: Advisory 508, 514, or 524; or call 1-800-4DRYLAB.

Any help would be greatly appreciated.

That's the "fallback" error-trapping routine. It means that the data you have entered have generated a math error (e.g., division by zero, log of a negative number, etc.). I spent 15 years doing tech support for the program. Over that period the most common cause was typographical errors entering data. Second most common was incorrect dwell volume (for gradient data). Third most common was insufficient equilibration time between calibration runs. Fourth was "unusual" chromatographic behavior (severe non-linearity). And, there were the occasional bugs (which the programmers were very good about fixing!) .

The first thing you should do is to check that you are using the latest version of DryLab. Click on Help . . . About to see the current version number, then go to the Rheodyne web site (sponsor link in the upper right-hand corner of the Forum, or: http://www.rheodyne.com). Click on Products . . . Chromatography Software . . . Latest Release.

If you are in North America, call 1-800-4drylab [1-800-437-9522] and ask for technical support. If you're outside North America, send me an e-mail (address below). Although I no longer work for Rheodyne, I still have a copy of the program, and I'll see what I can do.

the software does not produce the error if installed on Windows XP Professional....i am yet to have it work on Windows 2000 Professional....however like you said....the software may need to be updated, which i am going to try.

If you save the input data as an *.inp file (File . . . Save As in the data entry window) and then e-mail it to me, I can check it on both XP and 2000.

in the preferences > display > save laboratory state
then in Data entry.
when this feature is turned on, it gives this problem
