Compiling How can I make RME accept new data format?

[Lava Titan]

Well like the title says I wanna know where to fix the data format issue that I get when opening RME...

I already got the dat and spr signatures added in clients.xml but when I open rme it says max data format is 10.57...

I created folder 1090 in data and also added there 1090 items.xml and otb

<otb client="10.90" version="3" id="57"/>

<client name="10.90" otb="10.90" visible="true" data_directory="1090">
            <otbm version="3"/>
            <extensions from="8.20 - 8.31" to="10.90"/>
            <data format="10.90" dat="0x3F26" spr="0x565EE171"/>
        </client>
