1. Clean the battery terminals and connections.
2. Ensure the battery is fully charged.
3. Clean the connections going to the starter solenoid. If this doesn't solve the problem, you need to replace the starter with new one.

This problem apears when the battery has been diconected for some time. Start the car, and leave in in idle without driving it for about 10 min. The car runs fine after that.

Check that your battery is fully charged. If it does not sustain a charge , replace it. Clean the cables and battery posts with baking soda and water mixture. About 1/4 cup to a pint. If it still does not turn with a fully chared battery, it is probably the starter that is bad. It will have to be replaced. One click usually means the starter is bad. Several clicks usually means the battery is bad.

i have a spacestar and i found if you have plastic wedges around battery you have to prize them up from underneath the plastic wedge using your hand! Very easy (when you know how)

A late reply; I'm sure you have found the problem by now-
It sounds as if the battery (old and new) are not receiving sufficient charge.
Check the drive belt tension and add a cheap digital multimeter to your 'tools.'  These can be had for well under $20 US and you can then check across the battery terminals to see if the charge voltage is between ~ 13-14.3 volts at an idle. In no case should it be lower than 13 volts with the engine running since the nominal battery voltage is 12.6 volts when fully charged.
You may have a separate regulator that is ill.
