Last 2 orders not showing in admin - but received Paypal notification

Hi Everyone,
My website has been running smoothly for the last 2 years - tonight the last 2 orders do not show in Admin?

I have searched for what would be the Order numbers with no result - looked in Database and again no result.

I am at a loss as to why these 2 orders are not showing - Any ideas?

I did recently install COWOA and Recover Cart Sales BUT that was weeks ago and customers have been able to check out with / without account and all going smoothly...

Any help would be much appreciated :-)

And just ran ipn check with the following results:

IPNCHECK.PHP - Version 1.3.9

IPN TESTING - Response Received via CURL -- COMMUNICATIONS OKAY

IPN TESTING - Confirmation/Validation response with fsockopen(): FSOCKOPEN() RESPONSE RECEIVED - Communications OKAY

Default method likely to be used for communications is: CURL, with the fallback method being FSOCKOPEN if possible.

Script finished.

If the connection is closed before the customer returns to your website, the order is not recorded (orders are written to DB on checkout success page). Bit weird to have two, but is there any chance the customers closed their browsers before they came back to your site?
