I'm new to Umbraco. I have just installed CWS 3.0.2 from the Umbraco 4.7.1.1 backoffice.

After the installation, I get 3 installation errors.

Package install error: System.IO.FileNotFoundException: Could not find file 'E:\OpenDataWeb\App_Data\72dfcad0-fd3a-42e8-bca2-4b43b49ee261\ff07bf15-f0a4-483c-8579-a7f14bd00db3_Thumbs.db'.

Are these error critical? Should I reinstall the package?

Thanks,
