Concerned about time between exams

Hello, I am trying to get my MCSA at present (exam 70-290 next week). Previously I took and passed the 70-270 XP exam about 2 years ago and am concerned that it has since become invalid. Can anyone else confirm this? Also, as I lost my original MCP ID years ago it is not officially recorded anymore...all I have to prove I passed it is the printout from the passing centre. Help!

Give them as much info as possible.
e.g Name, e mail, contact tel number, test centre where you took exams, exam codes you believe to be on your transcript.
Don't expect a swift reply though, normally automated response within 24 hours, something a bit more substantial a week or 2 later. Best to give them a quick call.
