Out of Bounds Value

I am using the excelent set of MMORPG resources available here. When trying to implement part 5 which details using magic spells i end up getting an out of bounds value fatal error coming from the bitstream.h file. The console log is as follows:

Client has selected 1533 282.41 132.09 178.477 0.20022 0.879115 0.432514

obviously this doesnt tell you much but it does show you the error. I did a search for this and nothing came up that was relevant. The one that came closest was this but it didnt solve my problem. I know its hard to determine the cause of this but I was wondering if anyone using the MMORPG resource has come across this and has found a fix. I heard that there was a fix that detailed solving this problem but was unable to find it. If anyone could point me in the right direction and or has a fix that would be greatly apreciated. Thanks.
