was wondering maybe someone can help with this one.

I'm trying to claim my tokens on Pinnksale after a presale. So, the problem is, every time I click on the CLAIM Button--- the metamask wallet gives me this message.

 " This transaction is expected to fail. Trying to execute it is expected to be expensive but fail, and is not recommended."

Does anyone know how to fix it ???

thanks)

From this answer by Lauri

What probably happens is that Metamask runs a static call to the contract with the same parameters, to simulate what would happen if the transaction took place. If it notices that the static call reverts, it gives you this error - because most likely the real transaction would revert as well.

So most likely there is something in the code which causes a revert with the given parameters.
