While I have always been around Mac's, I just recently purchased one for personal use and am not extremely savvy with all the specifics. In January I purchased a 15" MacBook Pro and downloaded the newest version of Office (2011) upon purchase. Today I opened up a document of notes that I had worked on last Tuesday and Thursday (saved upon closing each instance) and noticed that the portion I had worked on last Thursday was no longer there. To be honest, I kind of blew it off as an error on my part (maybe I didn't save? maybe i dreamed I actually worked on it?) until a friend had a similar problem this evening. My friend who purchased her 13" MacBook Pro as well as office 2011 at the beginning of february was finishing up her final thesis. After adding 5 pages to a document that had been in progress for quite some time, she saved the document and closed out. About 20 minutes later she remembered something she wanted to add to the document, went to open it back up, and everything she had worked on this evening was missing; however, everything from the past was still there as is. I was willing to pass it off at first when it was just me, but I feel that there is something going on now that it's two separate people, different machines, same application software. I feel as if this could possibly be a bug considering the new-ness of this version of office. If it had been an older version or even on a PC I would be able to troubleshoot a little better, but am very limited in my in-depth mac os knowledge. We tried searching for temporary files with no luck. Does anyone have any suggestions as to what could be causing this and/or a means of recovery?
