Gift card plug in update crashed site

Ahh please help! I updated the gift card plug in and it suddenly broke the site. All I get is this error: PHP Warning: is_readable(): open_basedir restriction in effect. File(G:\PleskVhosts\dreamcatcherdesigns.net\httpdocs/wp-content/plugins/G:\PleskVhosts\dreamcatcherdesigns.net\httpdocs\wp-content\plugins\gift-cards-for-woocommerce/languages/rpgiftcards-en_US.mo) is not within the allowed path(s): (G:/PleskVhosts//dreamcatcherdesigns.net\;C:\Windows\Temp\) in G:\PleskVhosts\dreamcatcherdesigns.net\httpdocs\wp-includes\l10n.php on line 476

It wont let me access anything on my site or the dashboard to undo it. I have no idea how to fix this ?? And of course within minutes of this happening my customers are messaging me nonstop complaining.
