For anyone looking for a solution to a similar problem:
* You should install a newer version of CodeSys (e.g. 3.5 SP19)
* Open newer version of CodeSys
* Import the project
* Click File > Save Project as
* Select the appropriate file type according to the target CodeSys version - in case of CodeSys 3.5 SP11 select

Library files (CODESYS V3.5 SP11) (*.library)
* Click Save

Now you will be able to open the .library with the target CodeSys version.
