Hi There, So I'm getting the above error on my Windows PC and have no idea how. I've uninstalled and re-installed both RuneMate and RuneScape about 5 times each now. I tried the renaming of the files as described here; but to no avail. Each time RuneScape is ran it creates a new version of .jagex_cache_32 so changing it to jagexcache is not working. I am able to run it on my Windows Laptop that runs the same operating version. The only difference I can see is that my PC boots off an SSD (C: ) and holds program data on a hard drive (D: ). The RuneScape client opens through Spectre though so I don't see how this would be the problem. Any ideas? Thanks for reading!
