I have the same problem.
The main PC with Sticky Password 188.8.131.52 works normally on Win7Pro 64bit.
Last month all my portable SP don't work.
I've tryed about 5 different USB flashcards - no result.
I've tryed about 5 different!!! PCs (and notebooks and netbooks) with different OSs (Win7 64bit, Win7 32bit, WinVista 32bit).
