Hi, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your Excel file issues. Are you using MS Excel 2011 for Mac?
Are these "old" Excel files stored in your local hard disk drive? Or in an external storage drive like a Flash or thumb drive?
Also, can I remotely access your computer so that I can directly assist you with these OLD Excel files issues while you watch?
Remote access is an optional additional service offer with a minimal one-time flat fee ($15) regardless of how long it will take me to fix the problem. We can resume any time without additional cost. It is safe as you will be watching your screen and we can chat right there, and it will be a faster mode of help.
Please let me know if you want this remote option. A rating is only required when we are finished.
Thank you for writing back with that information and thank you for your permission to do remote access. I will now send the formal additional service offer of remote access. Please accept it so that I can create our remote session. After accepting it, you will then receive the procedures to join me in the remote session.
