Hi, I'm new to rapidminer. But I get a really dirty error message when I try to open a process that I have saved. It's the same thing if I choose to export and then later import it or save it to the processes folder. I have been loaded som regular CSV files into the processes.

ok @Linus_Frosteryd I see what's going on. Yes as you suspected, your Read CSV operator is not liking your filepath due to the &# characters in it. You can see it in the XML in line 17:

hello @Linus_Frosteryd - very good to have you here. I have moved this thread to the Getting Started Forum - our place for questions from new users like yourself.

I'd be happy to help you figure this out. Can you please repost/edit with your process XML, datasets, etc..? You can see some helpful hints here.

@sgenzer Thanks! Newbies like me, need all the help we can get at the beginning! I have updated the post with the XML-code I using some datasets in CSV-format ?
