I found someone who had the same problem. Here was the fix:
1.Install recovery console
Insert Windows cd to the cdrom drive, hit start button -> run and type:
where d: is a cdrom letter. Follow instructions on the screen.
2.Reboot computer. During startup there should be a menu, something like:
1.Microsoft Windows XP Professional
2.Recovery console (or something like that, I have Polish edition)
Choose recovery console, enter administrator password, go to main directory:
type cd \
3.In the command prompt type:
set allowallpath = true
It should let you acces to the recycler directory
4.Go to recycler directory and to the subdirectory where are your unwanted files and type:
Then your files should be listed. Write their names somewhere.
You will have to do so with every file you want to delete
There is also a command:
set allowwildcards = true
but I'm not sure if you can use it with del command.
Here is another option
You can remove the files directly from Windows it self.
Use the commandpromt to go to the catalog and the use the command "attrib -s -h" on all the files, the you can juste remove the with the del command in the commandpromt
