I tested it with my own RABO-account and I encounter the same problem. So sorry, I can’t be of help with this problem.
In one of the threads on this forum, Lubos wrote that he prefers to get rid of the csv-import possibility because of the many problems it brings.
As mentioned earlier, I have for the ING and for the RABO bankaccounts Excel-sheets to convert a csv transaction file into the qif format. Everybody interested can get this Excel-sheet. All you have to do is send me a private mail message.
