Order Total Mods Error

[MissConfused]

I enabled gift certificates and now I receive this error in the Order Total Modules

Fatal error: Call to a member function format() on a non-object in /home/*****/public_html/store/includes/modules/order_total/ot_gv.php on line 49

Can anyone help?

I have never posted about this issue before.
I'm using version 138.a
No my site has not been upgraded.
I searched the forum and the only threads I found with the same problem as me did not help rectify my problem.
The problem started when I enabled gift certificates.
This is not my first store.

I'm using version 138.a

You really need to upgrade as known vulnerabilities have been known since approx Jul '09

Support for that old of a version is sparse
Hopefully someone still has 1.3.8a & knows something about this issue

Ok thanks for the reply, I understand I need to upgrade but at this moment in time it's not possible.

This is the code line that supposedly has the error, if anyone could help I would truly appreciate it since it seems my customers now can't use Gift Certificate Balances while checking out

$this->checkbox = $this->user_prompt . '<input type="text" size="6" onkeyup="submitFunction()" name="cot_gv" value="' . number_format($_SESSION['cot_gv'], 2) . '" onfocus="if (this.value == \'' . number_format($_SESSION['cot_gv'], 2) . '\') this.value = \'\';" />' . ($this->user_has_gv_account($_SESSION['customer_id']) > 0 ? '<br />' . MODULE_ORDER_TOTAL_GV_USER_BALANCE . $currencies->format($this->user_has_gv_account($_SESSION['customer_id'])) : '');
