[GRASS-user] wingrass7 start and location

[Pham Thy]

Dear all,
I have just installed Wingrass7 from 
http://josef.fsv.cvut.cz/wingrass/grass70/
When it is started the locations which work well with Grass6.4 version, 
there is the error: Unable to get current geographic extent. Force 
quitting wxGUI. Please run manual g.region to fix 
problem....Importerror: No module named agw.customtreectrl
Or when I make new location by Location wizard there is the error: .. 
[Error 2] No such file or directory: 'C:\\Program Files\\ 
GRASS-70-SVN\\etc\\proj-parms.table'
Please help me what should I do?
Thank you
Thy
