columns completely disappeared in explorer

Hi,

the columns in explorer have all disappeared, except for the data
modified column. It lists all the files in a folder but no file names
just the date, so its pretty hard to see whats going on.

I have tried right clicking on the column names to select more columns
but there aren't any options to do this, all the main columns have
disappeared. Even when I click the more option and get shown a list of
columns with check boxes there are no name, size, type options.

I have tired changing the folder type, and resetting the folder options
but nothing seems to work.

Also search doesn't seem to work in the explorer window. Everything
looks find in a the 32bit version of explorer.

Seems like a problem with my registry but I don't really know where to
start to get the column names back in. Any ideas, thanks for the help
