Error in Contract Module

[unidacom]

I have intalled the contract module, but when I try to create a contract I receive the following message:

Retrieving record by id contracts: found Query Failed:SELECT contracts.* , contracts_cstm.* FROM contracts LEFT JOIN contracts_cstm ON contracts.id = contracts_cstm.id_c WHERE contracts.id = '' AND contracts.deleted=0 LIMIT 0,1::MySQL error 1146: Table 'sugarcrm.contracts_cstm' doesn't exist

Any ideas how to solve this error?

I had solved the problem. Entering to the Studio and then to "Repair Personalized fields".

Thanks
