Model Size in Solver Foundation

Question

Hi, 

Recently, I needed to reinstall my solver foundation and Gurobi. Then  following error happens when I try to solve my model. I could solve this a week ago using solver foundation before reinstalling them.

"Model size limit has been exceeded for this version of the product. Please contact Microsoft Corporation for licensing options.
Limits: NonzeroLimit = 50000, MipVariableLimit = 1000, MipRowLimit = 1000, MipNonzeroLimit = 5000, CspTermLimit = 5000, Expiration = none.

Thanks,
