Firstly, don't start a new thread for the same problem - it makes it difficult for people to understand what you're asking if they haven't seen the original thread and it doesn't necessarily make it more likely that your question will be answered.

What exactly are you trying to do - can you give a really basic description of what you want to do? Are you simply trying to reference another assembly in a project, or are you trying to reference a COM dll. If you're trying to reference a COM dll why? Is there not a managed assembly that has this functionality in it - if there is it will save you a lot of headaches.

Generally if you want to add an assembly reference the easiest way is to right click on your references and choose "Add References..." (assuming you're using Visual Studio). If you want to load an assembly at runtime rather than statically, you'll want to look at the System.Reflection namespace.

Also, normally when you have errors and it asks you if you want to ignore and continue, what it's doing is using an old version of your program (i.e. any changes you've made won't be included). So it probably doesn't mean much.
