 Keep cool. The program is work in progress and there will be always bugs. Write a brief bug report and sent it to the author of the program. If possible sent the .all file too.  Keep cool.

-This is a common problem ​in Windows. The program ​uses the english notation for numbers (decimal point "​."​)In principle ​the program is able to work with other number formats but it is not tested very well. All files like measurement data and files with optical constants are working only with "​."​ as decimal point. ​The best thing is to to change the number format under Windows. +Check the number format ​in Windows. Especially the decimal point and use this format for importing data. The program ​is well tested by using the "​." ​as decimal point. 
 +Most of the other fileslike optical constants ​files are working only with "​."​ as decimal point.

 The second beam is used in the two calculation modes dichroic and asymmetry. ​ The second beam is used in the two calculation modes dichroic and asymmetry. ​
 It just means that in one calculation the ray has polarization 1 and in the other one polarization 2. In dichroic mode this means that the two separate reflectivities are calculated and plotted. The asymmetry mode does the same but in this case the weighted differences of these two curves are plotted. It just means that in one calculation the ray has polarization 1 and in the other one polarization 2.

-The matrix-formalism ​are faster as they depend on the incoming polarization only in the last step of the calculation. In the Parratt-Formalism ​it does not change ​the calculation time.+The matrix-formalisms ​are faster as they depend on the incoming polarization only in the last step of the calculation. In the Parratt-Formalism the whole algorithm have to run two times.
