Can't import a TypeLib I previously created and updated.

I've got a solution that I've gummed up rather well. The solution had a typelib in it and I made some changes to the typelib and wanted to import a new version of it into the solution. So, I re-published the typelib. Then I went into the solution and deleted the previous version. Finally, I attempted to import the updated typelib but it told me that it already existed so it would not be imported.

I've experienced this problem before, in other instances. I tried Recursive Sync, Revert, refreshing my browser, emptying cookies, etc. In the past those have worked sometimes. On one recent occasion none of those worked, but I was able to solve the problem by re-importing the *entire* solution into a brand-new solution. Sadly, however, even *that* didn't work in this case.

What can I do?

I have many other things I can work on, but I do need to get the new version of my typelib re-imported into my solution. It's been in this state for four days now. (There was a holiday, I realize, but not any more...)
