Thanks for the help so far.
I've made a copy of the wallet.dat file. I am used to that anyway, as I use multiple computers, and use my wallets on those computers.
It was a bit of searching to find the wallet.dat file in the beginning,  but it turns out that a lot of my coin wallet.dat files are stored in the user/appdata/roaming folder.
That folder was not easy accescable, I could only acces it via the search function in windows. I've made a link to my desktop in case of further use.

Cheers guys !!
