Any reason, Why Matlab R2007b support fixdt(1,16) OR fixdt(0,16) but not Matlab R2010b?

Hello..
I was working on one of the fixed-point model on R2007b, which was having some of the data-objetcs with fixdt(0,8) and fixdt(1,8) output datatype. This model was simulating fine in Matlab R2007b but the same model when I was trying to simulate in R2010b, it was throwing me an error saying ' not supported dataype', So I would like to know the reason behind this.
Please help me out.. Thanks in advance..

Do you have a Simulink Fixed-Point License on your R2010b? Also, please paste the exact error message from the software.

Hello Kaustubha,
Yes, I have Fixed Point Licese on my R2010b.
I am getting following msg while running model on R2010b but same model working fine on R2007b.
'fixdt(0,8)' resolves to a fixed-point data type with unspecified scaling for parameter 'OutDataTypeStr' in 'CommunicationsBusInterface_TL_sl_2007b/ControlModel/Signal_Conversion_Rx/conversion COMRX_CmdIgnStat/COMRX_CmdIgnStat_Temp', but such data type is not supported by this parameter.
