You can look in the options screen of CSM if the paths are correct.
If that doesn't help, then go to the about screen and you'll find an email address for support
keep in mind that 1.25.55 is a non supported version because it was just a 'teaser' and to allow tony to have some limited track support.
if it works, you're lucky if it doesn't, then there are no guarrantees i'll try to solve the problem.
That doesn't mean that i
won't solve the problem.
If it's a bug in CSM then i can always look at it and possibly, send you a fix.
But i won't put in a lot of work in 1.25.xx anymore because i'm finishing 1.26 which has been written from scratch, only using some small parts of the old code.
I'd rather have a bottle in front of me than a frontal lobotomy
