Thanks, Andrew. It was indeed a permissions issue. In order to troubleshoot
this (as symlinks can be tricky), I copied the index files and registry
into the CQPWiaB VM and placed them into the same directories as the BNC
sampler and Mandarin corpora. The problems persisted, so I changed
permissions and ownership as follows (replace test_flxml_corpus with the
name of your corpus):

cd /var/cqpweb/index
sudo chown www-data:www-data test_flxml_corpus
sudo chmod 755 test_flxml_corpus

cd test_flxml_corpus
sudo chown www-data:www-data *
sudo chmod 644 *

cd ../../registry/
sudo chown www-data:www-data test_flxml_corpus
sudo chmod 664 test_flxml_corpus


So now I can attempt to import the corpus, but I run into a new error:
"Pre-indexed corpora require s-attributes text and text_id!!".  I've
searched the manual included in CQPWiaB but there's no mention of
"text_id". What am I doing wrong?

Below is the content of my registry file, in case that helps.

Thanks!
Scott
