when I select multiple text files and execute to import into new worksheets, I see those sheets being generated but they disappear right away. But, they gets imported into new colums in one worksheet. This had been working properly until a while ago. Also, when I execute import wizard, nothing happens.
Thanks for the note. What I don't understand is reintallation doesn't help, which seems to make no sense because reinstallation should bring it to the privious status.
