Mbed Studio 1.4.2 linter bugs

Hi.
We are also having problems. All worked OK on 1.4.1 but after update Studio to 1.4.2 Lint cannot find many header files (such as stddef.h, stdint.h and so on). Same question: where to find older version installation or what have to be done to solve this problem on updated version??? Big project has stopped… If we do not have any solution in a short time we will have to change IDE to some other one…
