Failed to Open Stream

After completion of the Conference Organizing install-script, I encountered these problems:
· warning: file(./profiles/cod/cck/conference.txt) [function.file]: failed to open stream: No such file or directory in ./profiles/cod/cod.profile on line 243.
· warning: implode() [function.implode]: Bad arguments. in ./profiles/cod/cod.profile on line 243.
· The import data is not valid import text.
· warning: file(./profiles/cod/cck/profile.txt) [function.file]: failed to open stream: No such file or directory in ./profiles/cod/cod.profile on line 243.
· warning: implode() [function.implode]: Bad arguments. in ./profiles/cod/cod.profile on line 243.

and so on for every of the .txt files in cod cck.

I then could proceed, but only edit the account. Other functionalities are not present. Error messages on the "running" system are:

* warning: Invalid argument supplied for foreach() in /profiles/cod/modules/views/views_query.inc on line 81.
* warning: Invalid argument supplied for foreach() in /profiles/cod/modules/views/views_query.inc on line 16.
* warning: Invalid argument supplied for foreach() in /profiles/cod/modules/views/views_query.inc on line 195.

with these lines around line 80 in the inc:
