WAsP Map Creation Problem


I would like to create a WAsP elevation+roughness map and I need help urgently. 

These are the steps I did: 

1) Download Data ASTER GDEM v2
2) Download Data Land Cover Corine 2006
3) Analysis-Create Contours
4) Create Elevation Grid
5) Open Control Center-Right Click to Land Cover Corine 2006- Create ROUGHNESS 
6) Export-WAsP

First problem: It takes 24 hours to complete a map. 
Second problem: The map on WAsP seems with many unneccessary lines. (Because of roughness) 

Can you please tell me the steps I should do.
