It seems like it's having problems copying the map to the maps folder
[quote]** Executing...
** Command: Copy File
** Parameters: "\SVEN_Test"
  • Could not execute the command:
Copy File "\SVEN_Test"
  • Windows gave the error message:
"Access is denied."[/quote]
and therefore when it tries to launch the map it can't find the required files
** Executing...
** Command: D:\PROGRA~1\Steam\STEAMA~1\cheese\HALF-L~1\
hl.exe
** Parameters: +map "SVEN_Test"

Windows Error.

Are you running Vista? If so try running the program as Administrator or even better disable the User Access Control "bug".
Then again I might also be completely wrong
