It is not clear what you are asking exactly nor trying to accomplish, but I will try to help you as much as possible:
- to have a plot showing all the required coefficients and Tminimum+Tmaximum must be entered. No plots will show if you don't. It is not clear whether you are trying to get a plot for a new compounds T correlation or whether you got it, exported it, and then are trying to re-import it for some reason. Being more clear in your intentions will allow me to help you.
- typing data on the imports panel directly in the edit window currently doesn't yet convert it to data on the plot, as it still needs implementation. Here you have to realize that these panels are still in the progress of being further developed (where needed). Similarly, there is a bug in the ability to save plots on the < Import > tab panel; I have logged it as a low priority bug.
- items on the < = > panel are for plotting with the "plot" command in ChemSep (only).
- the fit iteration count can be reset by switching to another T correlation or component.
- the messages you mention seem to indicate that you didn't install ChemSep properly somehow. First try de-install ChemSep and then to download ChemSep LITE from the http:/www.chemsep.org site and run the installation. If you are the only user, you do not need to install for everybody on the machine, the advantage being that you don't need system admin priviledges under Win Vista/7/8. If these messages persist, please let me know.
