I am using WUBI and have no CD, I have GPARTED but cannot mount partitions

Hmm, okay, there's not a lot to go on here...

Lemme piece together what I think the problem is.
You "installed" Ubuntu - on windows. Linux partitions its disks, one of those partitions is swap space. I suspect two things, either there is no swap space (at all) in the "disk" where Ubuntu is installed, or the swap scpace was configured ... too small to begin with. Linux needs to store stuff before going into hibernation...
Several options are open to you:

Use VirtualBox, I have some great experiences with it, so I can recommend it
Reinstall Ubuntu, but pay attention to increase the swapspace, if at all possible
Install Ubuntu on a second-hander/hand-me-down and (eventually) forget about windows altogether...

Good luck, and I'll keep this thread on the radar!

wubi is not exactly a linux install.

If you need to hibernate then you need a real install to a partition.
Consider also a virtual machine if you have a modern fast system.
Consider installing to usb drives if you don't want to mess with your normal os. Live usb's are pretty good for most people.
