HEC-GeoRAS Export RAS Data - empty message window

[MartaLustyk]

Hi,

I just start working with HEC-RAS and I've got problem with export my ESRI files to RAS. I do complete pre-processing in ArcMAP 10.2.2. (I use HEC-GeoRAS 5.0.3) and everything was great until I have to Export GIS data to RAS: Export RAS Data. When I click OK ExportRASData window is empty like below:

Due to I can't continue work in HEC RAS, because I have no files to import.

Before, I pre-processed data by tutorials on youtube  and paper tutorials and I have got the same problem on the same step. When I check data in attribute tables in feature classes according requires in tutorial  for me everything is fine.

Have You got any advices where is the problem or what where I do mistake?

More screens from my project:

XSCutLines3D

(I know that it it should be drawn more precisely, but I did it so many times and never work, so now I just want do achieve correct export.)

Regards, 

Marta
