Excel importing, I get error when trying to export to Spira Test and using the very same steps as directed in the video

Good-day,

I get the following error message when trying to export my excel template into spira test, is there something that I am doing wrong as I am following the exact steps being shown in the youtube video for exporting?

Message Below;

• Export failed with 79 errors. Please look in the column to the right of the
  data for the appropriate error message.

Error in the excel template message;

• The message filter indicated that the application is busy. (Exception from HRESULT: 0x8001010A (RPC_E_SERVERCALL_RETRYLATER))

What do these mean and am I doing something wrong or have I missed out on something? Please help

Regards
