Windows 7: deskspace hide icons from taskbar

Hi to all, m facing very strange issue.

I have just downloaded the trial version of DeskSpace which shows multiple desktops.

now what happened here i have so many programs opened and were displaying on taskbar.

But i dont know suddenly what happened and my programs get disappeared.

Those program are showing in the Task manager 's process tab. those are running but icons anr missing in the task manager.

some of the programs are my incomplete work so i cannot restart my computer.

Please suggest me what to do?

i tried by closing the Deskspace but not working

Right click on the Desktop, select View then Show Desktop Icons???

If no help, start DeskSpace again then check the other Desktops, see if the icons are there.
