After first starting eJuice Me Up and before opening or entering a recipe, go to "Tools", "Grams Set" and enter your values then click "OK".
After entering values, go to the top menu "File", "Save As Default" keeping the file name "Default.dft" so that the calc will remember the settings for each new recipe you create.
If it's an existing recipe, you will have to enter the gram weights then save the recipe to retain.
Important:
The key is to save as Default.dft it must be exactly like that and not Default.dft.dft Also it must be SAVED in the folder in which the eJuice Me Up program was installed in.
