Double pane windows rely on an airtight seal to work correctly. Condensation between the glass plates is a typical sign of a failing seal. Condensation between glass plates are not a major problem and can be corrected however, it's a sign that your glazing unit requires replacement. If you have a double-glazed window that is old, it might be necessary to replace the glass as well as the frame.

Glass is brittle, and it's not uncommon for double-pane windows to crack as time passes. If the cracks were not caused by mechanical damage, or an unusual impact on the window it is possible to repair them with epoxy and elbow grease. Begin by cleaning the cracked area with a wet cotton rag. Then, apply epoxy to the crack, following the manufacturer's instructions. Allow the epoxy to completely dry before sanding and painting over the repaired area.
A simple strip of masking tape can also be used to stop cracks from spreading.

If you notice deeper cracks in your glass that are already present, it is recommended to speak with an expert for repair.

Condensation Build-Up
The good fact is that condensation between window panes is normal. It's caused by a difference between the temperature of air and humidity levels and causes water vapour to condense upon contact with cold impenetrable surfaces such as windows. This is generally a good thing during winter because it stops the loss of heat.
However, if you're finding that your windows are appearing cloudy with a film of water on them, it's probably time to call in a professional glazier. This is a sign that the 'air gap seal between the two glass panes is beginning to break down and allowing moisture into the window.
You can stop this by using dehumidifiers, enhancing ventilation, or by applying de-icing agents. There are also professional companies that can help repair condensation build-up in double glazed windows by drilling holes in the window unit and injecting or pumping special desiccant to remove the excess moisture. This is a more complex procedure that requires the unit to be removed from the frame, and then opening each pane of glass and thoroughly cleaning them, then refilling with desiccant before sealing them back up. This is typically more expensive, but it's important to make sure the company you choose is insured and is registered with FENSA.
