DESTester not working

Without re-compiling, I tried DESTester on my XEM3010-1500. I encrypted a text file, then decrypted to a new file. The new file is unreadable.

Everything appears to be successful, but the result is not correct. I have also had problems with RAMTester, but only intermittently.

Has anyone else had this problem? Any ideas?

Thanks.
