Error: Can't modify read-only field

Hi,

I have got an error when compiling project:

------------------------------------------------------------------------------------------------------------

Can't modify read-only field

Correct any script errors in C:/dvsdk_1_11_00_00/MyProjects/Contrast_image/video_preview.tcf
using the Configuration Tool or a text editor, if necessary.

TConf initialization arguments:
-e environment['config.importPath']='.;../common;C:/CCStudio_v3.3/bios_5_33_05/packages;' -e environment['config.scriptName']='video_preview.tcf'

------------------------------------------------------------------------------------------------------------

What does it mean, what I need to do?

Thanks,

Igor
