Model incompatible with server; import a newer model. Model version: 1.4.3

hi,

I have installed EP 7.0 on MSSQL server 2005 using JAVA engine.

I have deployed the support package stack 15 and is was deployed sucessfully.

When i look in to the url http://<hostname>:50000/sld it is showing the below error

Model incompatible with server; import a newer model. Model version: 1.4.31 Server requires at least: 1.5.24

My problem is i was unable tp configure SLD inmy EP 7.0 system.

please do the needful.

Thanks & Regards

Mohammed
