So, I have it "working" now. On my work computer, running 10.8.5, it is running fine with no issues at all. On my personal computer, running 10.9, I can now open the Microsoft documents fine. However, with excel documents, when I save it, I get the following:
Document saved successfully.
Cannot reopen the saved document due to low memory. Please close the document.
This only happens with excel documents in Boxcryptor. Thoughts?
