Will i lose my no claims bonus?

the drivers side window of my car was smashed today after calling around for prices i was told that it would be a few days to get the correct glass but i need my car for work so i contacted the insurance company lv who will repair it tomorrow morning first thing, i have paid the 75 excess but now im worried that i will lose my 3 years no claims bonus for something that was entirely not my fault, i have just bought my 4th years insurance in april and you cannot get no claims protection untill you have 4 years no claims according to lv so next time it would have been protected, im a very safe driver and have never had an accident, so my long winded question is this, if you claim for a smashed window does it still count as having had an accident and therefor negate the no claims
