My program loads for like a second then says the error. It's been working fine ever since the initial install several months ago. Then today this...? HP laptop running windows 8
Error -59 usually means the installation folder is corrupt.
Try running the installation process from the disc again - if offered select the Repair option and proceed from there.
If this fails then:
Using Windows Explorer search for musicmaker.ini - you will have to set the search to include Hidden and system folders.
You should find 3 instances of this file - the one you want will be the largest in size - delete it.
Start Music Maker.
If it still fails then you may need to do a clean install - see this tutorial for fixing Windows 10 errors do steps 1,2, 11 and 12 - it is very important to do step 2 otherwise you will be back to where you were before re-installing.
