Thanks - i will try
Hopefully you bought from Dim3nsioneer. They have awesome support. You will almost surely get free replacements for all 4 blocks.
While waiting for your replacement you can print this to get going again:

Hi and welcome,
You can contact you reseller for this. These parts came with the first Ultimaker 3 printers and had an issue with strength (as you see).
I would think these should be replaced by your reseller without cost for you.
The spare part is called sliding block half (and needs two to make a sliding block).
