I'm down to 2 compiler warnings

I felt like getting rid of all my compiler warnings today but I've got two left.

"A custom tool 'MSDataSetGenerator' is associated with file 'dsContracts.xsd', but the output of the custom tool was not found in the project. You may try re-running the custom tool by right-clicking on the file in the Solution Explorer and choosing Run Custom Tool."

I have this error on dsContracts.xsd which is in one of my projects, and a ds.xsd in another one of my projects. I have tons of other xsd files which are fine.

Why these two? How do I "fix" it?

I love how they half-heartedly tell me how I "may try" something. Needless to say, it did not work.

I've been developing this solution for a while. I don't know how long this has been there because I've been ignoring my warnings, but I did get a new laptop last week and the IT person moved all my software onto it. I don't know if that has something to do with it. But it's odd that 2 files give me this problem and 50 others are fine.

Thanks!
