Thank you so Much guy, you helped me a lot.The order of blocks and items in the xml file is important. You need to place new blocks that extends from another block "after" that block in the XML file. So the block you are extending from must have already been read in the file before the compiler reads the new block you made. You will notice in the xml file that all the "master" blocks are at the top/beginning of the xml file. That is why.
This is the block.<block id="2550" name="QuarryPlatform Resources"><property name="CustomIcon" value="cntShippingCrateShamway"/>
<property name="LightOpacity" value="0"/>
<property name="Material" value="Mmetal_medium"/>
<property name="Shape" value="New"/>
<property name="Model" value="cube"/>
<property name="Mesh" value="cutout"/>
<property name="Texture" value="310"/>
<property name="RotationAllowed" value="pivotOnFloor" />
<property name="Class" value="UpgradeRated" />
<property name="UpgradeRated.ToBlock" value="QuarryPlatform Resources2" />
<property name="UpgradeRated.Rate" value="1" />
<property class="RepairItems">
<property name="wood" value="10" />
</property>
<property name="MaxDamage" value="10000"/>
<property name="Stacknumber" value="1"/>
<property class="RepairItems">
<property name="wood" value="1"/>
</property>
<drop event="Destroy" count="0" />
<drop event="Harvest" name="QuarryPlatform Resources" count="1" prob="1" />
</block>

So Who Id i Can Use?You forgot that the last useable block id is 2047, because only 11 bits are used for storing of block id in the map data.
Open up the block.xml file and starting at the top, look for the first unused number. There is a large number of open blocks ID's beginning at 74So Who Id i Can Use?
