The HPL2 engine causes processor clock interuppt.

[Rector]

Greetings!

I've been working on my custom story for about a month now, using both Amnesia TDD, Justine and White Night Conversion models for it. However, it has become quite a big problem recently when I, about 1-20 mins using the editor, recieve a blue screen saying "a clock interrupt was not received on a secondary processor". It's always the same BSoD and it doesn't matter if I'm using original Amnesia models only or together with WN.

My components are:
Intel Core i5-3570k 3.40 GHz (quad-core)
AMD Radeon HD 7870 2GB RAM

I've checked the HPL2 editor version, it was downloaded 7/2-2013.

I've been using the editor just fine before the BSoD's occured, which was about a month ago. Were using the WN models back then too without any issue.

Any help is highly appriciated!
Kind regards!
