Can't reindex with sunspot / solr in rails app - Error: Severe errors in solr configuration

Ok, so I have a simple rails application and now i'm trying to implement sunspot for search capabilities. However, after I've generated the config file with rails g sunspot_rails:install and after I've started the server and it has made the solr-dir in my rails app-dir and i run bundle exec rake sunspot:solr:reindex I get the following trace: ``` cakism@saraswati:~/railscode/calendar$ bundle exec rake sunspot:solr:reindex --trace ** Invoke sunspot:solr:reindex (first_time) ** Invoke sunspot:reindex (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute sunspot:reindex Skipping progress bar: for progress reporting, add gem 'progress_bar' to your Gemfile rake aborted!

Other posts with the same problem as I have has specified the solr/conf/solrconfig.xml, and also, when I change it to false, nothing else happens. If I remove the searchable block from my model, I don't get any error (but I suppose that's because it doesn't try to do anything then) I've run the config file through an XML validator, and it says it's bad start-tag name at 2<-1 5<-2 6<90%. However, even if I remove the lines which then gives a valid XML, restart solr, and try to reindex, I still get the same error. I'm starting to get desperate here, so any help is greatly appriciated!
