Epoxy moulding paste problem

Hi, I recently bought a 5k tub of epoxy moulding paste and hardener as part of an order.
When I opened the tub to use it today the paste was rock hard. I had already coated my parts with the epoxy tooling gel coat so I cut some of the paste out with a knife to attempt to use it. I thought the hardener may soften the paste to enable me to use it. After about 15 minutes of mixing I had to use the paste as the gel coat was setting. Even though I had worked the paste it still had hard lumps in it which I’m sure will affect the outcome of the mould.
So, the question is, is there something I can use to revive the paste or do I need to send it back to you?
Just to confirm, I bough the paste & gel coat with their hardeners last week and broke the seal on the paste tub today.
I have previously used your moulding paste and it was very pliable, like paste I suppose. I’m just hoping all my hard work setting up the work piece hasn’t been in vain!
Please advise me of my options,
Regards
Roger

Hi Rich,Thank you for your prompt reply. I’ll put the paste in a nice warm environment as see how it goes. If I find it doesn’t return to a more fluid state I’ll get back to.Kind regardsRog

40°C in the curing oven overnight should be fine to get it back to life.
