hello i just installed unity and when i launch it i get this error popup : Fatal error! type == kMetaAssetType pathName.find("library/metadata") != 0 please note that i never launched it before, it crashes since the very 1st launch, so i never got a chance to open and try the default project.... thanks for your help Vince
well to be more precise, i installed unity 3.5 then i saw a demo of unity 4.0 so i uninstalled 3.5 then installed 4.0 then it asked me a key i didn't have so i removed 4.0 ans installed again 3.5.... then i cannot open it
well i fixed it i searched in regedit and found references as "C:\Users\Public\Documents\Unity Projects\4-0_AngryBots" for the latest project so i modified it to "C:\Users\Public\Documents\Unity Projects\3-5_AngryBots" and that's ok now...
I found a small workaround not sure how effective it is as of yet, i'm still importing but deleting the contents of meta-data seem to un-corrupt the project.
For those who are confused about how to fix the regedit values : open up regedit by typing it into start (not sure of this works in windows 8 ) the press control-F and paste the following C:\Users\Public\Documents\Unity Projects\4-0_AngryBots then find the files with that extension and right click on them and click modify then replace the numbers 4-0 with 3-5 do this for all three then open up unity and enjoy
