ACS error

[Guest]

When logging off my windows embedded device (hp nc6000), I keep getting an
error:

ACS.exe application error, the instruction at "0x100227ca" referenced memory
at "0x00000004". The memory could not be "read". Click OK to terminate the
program.

Afther a login, my wireless connection does not work, because ACS is the
service that provides me with LEAP acces. Does anyone know how i can get rid
off the error and use my wireless network normally????

Thanks for any response,
