removing this order limit per day

Hi I installed this plug-in and I need that users should be able to buy products with limits set up for groups and that these limits are daily. This succeeded in doing so but there is the problem that these limits are for only the first order, if they try to do another order on the same day it does not allow it, considering the fact that already in the first order they had no daily limit of number of products set.
I give an example
User 1 has a daily limit of 18 products if it enters the morning and makes an order of 5 products then if you feel the afternoon to enter to make another order because they remain another 13 products does not do it.
Is there the possibility of removing this order limit per day?
