Solved New Blue Styilizers

Looking for some sound and experienced advice please. I have contacted NewBlue  support with the following problem.............I purchased Stylizers 5 from Magix as a bundle with Vegas Pro some time ago and all has been working OK up and until I purchased Magix Movie Studio 2023 to teach my grandson on how to use a NLE which included Sylizers 5 Ulimate (which works fine after installing in this program) I now find I cannot use my NewBlue Stylizers in Vegas Pro19. All I get is a red circle with a line through and I cannot drag the effect the timeline without the program just closing.

They replied........... would recommend clearing your Vegas plugin cache:
1) Close Vegas
2) Delete plugin_manager_cache.bin and svfx_plugin_cache.bin from 
C:\Users\{user name}\AppData\Local\VEGAS Pro\<version number>, 
3) Then retest..
My question is.  Is this safe to delete these files and follow the given advice?  I had a problem with Vegas Pro 19 not running on my PC and sought help from Magix support which sadly resulted in me reformatting my hard drive re-installing Win 11 and all my programs.  I don't need this sort of experience again at my age sadly.  Cheers John
 

Yes it is safe to delete any files in the VEGAS Temporary Files Cache/Folder.
Anything deleted in this folder will get auto-regenerated next time you open VEGAS, which often fixes most problems with 3rd Party FX not working properly.

Thanks for the reassurance Derek, Performed and all is Ok now.  cheers John
