Hi All, I have been stuck for weeks trying to solve this issue to no avail and I hope someone will be able to help me out! I am using an application called eSignal for stocks and forex and since it doesn't support Mac I installed it on Windows10 using Parallel. It was working for until few weeks ago when it stopped loading "Formulas" files located on the Windows10 and it is giving me the error below: Y:/Documents/Interactive Data/Formulas/las/Relative Strength.efs: Error: Function 'efsInternal': Failed to get access to 'Y:\Documents\Interactive Data\Formulas\las\Relative Strength.efs' file: insecure path. Please use files from Formulas directory '\\Mac\Home\Documents\Interactive Data\Formulas\' instead. You can ignore the specifics in the error message above but the point is I have installed the application in the correct folder on the C drive and when I browse from within eSignal to the Formula file to load it is always giving me this error. Does this indicate an underlying issue with Parallel? I have just upgraded to Parallel Desktop 13? Thanks in advance,
