I will try to help, maybe we can at least get your taskbar back.
Do you have a Windows keyboard? There should be a WinLogo key between the left control & alt key. The Menu should pop up, select Cinnamon settings, then Panel. On Panel layout, select 'Traditional', then select 'Use customized panel size' and making it larger. Maybe that'll help, let us know what happens.
I don't mind going to work, it's that 8 hour wait to go home that sucks.
