Perhaps this will help some French Canadian users… I was getting that error that I had already had with American Express.
I deleted the connection information, but I was still getting the same error. I found here in the community that there is a CONNLOG.TXT file available from the Help→Contact Support→Log Files that was reporting on some missing TRNTYPE. I opened the .qfx file from Tangerine to find that it was there, but with a CRÉDIT value. I guessed that Quicken does not like accented characters when it parses the content so I changed my language to English on the Tangerine Web site, downloaded the file and then it worked…
I always forget how English speaking organization neglect the rest of the non-English world… a new recall.
