Fl studio crashes when trying to open vital in the chanal rack

I bough some presets from onpointsamples and wanted to use them. But my vital is on the oldest version the 1.0.7. (Which opens fine and I could use normally without problems) the presets are made one a newer version of vital, so I deleted the old version en downloaded the 1.5.5 version. I added it to fl studio just like I did with the older version. But when I try to open vital it opens half and after a couple of second it crashes an closes FL studio. I realy want to start and make some music. I have been on this problem for 3 days now, trying to figure out what is happening. I hope someone on this forum can help me! Thanks a lot.

Hey
Is there any way you can try a full re install?
Just want to make sure you clear all the old vital stuff perfectly before installing the new version
Sometimes this can cause issues.

Otherwise, does Vital standalone open fine, is it just FL or Vital also crashes alone?
