Sadly, fixing some state restore issues in various hosts required changing the way presets are represented, which means that patches created in any Olga version prior to v1.00.03 will not load in v1.00.03 or any later version.
But the doctor is in. If you have any patches saved in earler versions that you want to convert, post them here (or PM me) and I can convert them to v1.00.03 (and later) format. The format will not change again.
Thanks!
