Hi,
There is indeed a problem with zeros before the comma in prices for moneybookers.
Could you change the code:
$vars = Array(
		"currency" => $currency->currency_code,
		"amount" => trim(trim(round($order->cart->full_total->prices[0]->price_value_with_tax,(int)$currency->currency_locale['int_frac_digits']), '0'), '.'),
		);
to:
$price = round($order->cart->full_total->prices[0]->price_value_with_tax,(int)$currency->currency_locale['int_frac_digits']);
		if(strpos($price,'.')){
			$price =rtrim(rtrim($price, '0'), '.');
		}
		$vars = Array(
		"currency" => $currency->currency_code,
		"amount" => $price,
		);in the file plugins/hikashoppayment/moneybookers.php and try again ?
That should solve the problem.
