Google Analytics tracking id error
We have Google Analytics set up on our website and it is great for our reporting, but for June and July it wasn't tracking correctly. I checked in June and looks like there was a tracking id error. I replaced it again, made sure the site and Google Analytics were the same. I checked again later and looks like it didn't work. It only tracked 289 hits for June and July when our normal hits are 5,000+ per month. I re-did the id again and for August 1 - 4 it has already tracked 300 hits. so clearly there was an error with the id.
Basically my question is, is there a way to recover missing data? June and July aren't listing correctly and I need this information for our company reporting.
