.. However, I am not able to view the code modifications in the Gujer matrix ..

This is most likely because you have not 'regenerated' the [b]BlockLib.xml[/b]
The steps you describe are essentially correct, but let me first clarify one or two details.
Once you've modified the code (I assume you have done so through the Matrix Editor, right?) and before you check the library: have you saved the changes?
E.g. [i]by closing the Matrix Editor, you will be asked to save; since you had already created a new [b]category[/b] "ASM_X", you do not need to rename[/i].
Step 4 (library check) has no relevance, until the block library has actually 'acquired' your new category - which does not happen automatically in W2014.
So, after your step 3 (and after you saved the conversion model):
[list]
[li]add a new [b]instance[/b] to the block library (from the Block Library Explorer menu)[/li]
[li]the new instance does not need to be called "ASM_X", although this has been generally the case so far[/li]
[li]associate the new instance to your new category (cf. Category DisplayName and Value properties)[/li]
[li]make sure you also provide a PaletteLib for the new instance - otherwise you will not be able to use it to create layouts in WEST[/li]
[li]save the Block Library[/li]
[/list]
Now, you should be able to view the Gujer Matrix for your new category.
