Anyone had problems activating this using KMS servers or Internet?

Had a call this morning, previously activated PC with Office 2010 on it, now asking for a valid key. Went along with the valid key to initially be told it was not a valid office installation key, tried a different method and it took the key and went through the process as if it was activating. Closed Word, opened back up and it instantly asks to authenticate, when trying I get an error message 0x80070190, which appears to point to a problem with UAC requiring elevated privilege to allow activation.

Haven't tried the solutions yet, use at lunch until 1400. Anyone else experienced this?
