Cannot create a file when that file already exists. (183)

[gerryc123]

Hi all,
I am having a nightmarish problem with only 1 Plug-in out of over 100.
My XLN Addictive drums when I save my plug-in preset ANYWHERE I keep getting this Error. XLN has been great they have really looked into it and they swear it's a Pro Tools permission problem.
Pro Tools tech support has been horrific, I have been waiting 4 days for them to call for remote support and they are doing my head in. They email to ask if I'm available and I respond yes and sit by my phone for HOURS!!!!
4 Days in a ROW!!

Does anyone know what can be done about this error.

I am on Windows 10, 32GB all the bells and whistles. The error is as follows

Cannot create a file when that file already exists. (183)

It seems to be a permission issue but just when I think I got it , it just keeps happening.

It has been going on for months. I surrendered my perpetual license to go for the subscription in the hope some more money would fix the problem it hasn't. I am using the latest version of PT as well.

Any ideas??
Thanks
