Whenever I try to run Squawkbox with FS9. SBRelay and suc already done, I get this error message: 891111 Illegal read attempt: offset 0354, size 2891111 ... Program or module not accredited for use with this unregistered FSUIPCNow I understand what that means, but do I HAVE to buy FSUIPC to use FS9 on VATSIM?And if not, how?

No SB2.3 has a freeware code for it, all you need to do is register the freeware code for SB with FSUIPCProduct: "SquawkBox 2.3", Company: "None" KEY = LWVQ 7I2V 9GPBClick on register app, not register FSUIPC if your asked for a email address you on the wrong page.
