If you backup your database ...
Go to phpMyAdmin ...
Look at the structure of the orders_products_attributes table ...
Edit the field products_options_values and change from BLOB to TEXT ...
NOTE: I have not tested this 100% but at the moment I am not seeing any reason that this would not work for you so that you have a large field capable of holding anything that the products_options_values could hold before but this lets you view it in phpMyAdmin ...
I have to chew on this a bit and consider if there is any reason why this couldn't be changed this way ...
NOTE: you may wish to use a test site and test database and make the change on there and then conduct a lot of tests and examin your old data and see if you see anything obvious that might be moofed up ...
But, like I say, I don't think this will be an issue ... but again I have not tested it 100% ...
