Hi @Jon_Colman
The FR server hosts their own forum for support and that reaches the administrators (looks like they didn’t see this here). You should be able to post in English and they can translate.
Let us know if you have any trouble with this and we can try to help get this communicated. Is this the Datatypes → Convert → fastq uncompressed-to-compress action? Or that same tool from the tool panel? Or something else? Was the output from a tool (which?) or was it Uploaded?
Thanks!
