SanDisk Cruzer Problem

I purchsed a couple of SanDisk flash drives not realizing that they encrypt all files. While I got that problem solved by formating the flash drives, now my MS Works files all become encrypted when I transfer them via email, etc. My MS Works program is from MS Office 2000 which is not encryptable per MS. Somehow I believe the SanDisk drives had something to do with this as I've been using Works for many years w/o any encrypting. Of course SanDisk techs say it's a Works problem since their drives are no longer encrypting files. Anyone know how to fix this?

 

Operating system is Win 7.

 

A little further info on this problem is that when opening Works documents in M/S Works program (desktop shortcut), they ARE NOT encrypted. When opening Works documents from the Library, they are encrypted. Again, OS is WIN 7. All I want to do is remove all encrypting.
