:-( Ooops... Only the culprit I can imagine is TAP-Win32 adapter v9 network device.  Does it show some detailed information about why?

Nope it doesn't show any information. It's not like it happens instantly i happens like 12-24hours after i install Mudfish which really sucks. I have no problem using the software but it's causing me to have to reinstall windows at least once every 1-2 days I really don't want to have to stop using Mudfish because its a life saver but I've been spending days trying to find a fix and i really don't know what to do. Ive tried installing the 32bit version (i run 64bit OS) to see if that would make any difference but at the end of the 32bit installation i get " An error has occurred installing the miniport adapter" The last thing i can think of is downloading a older version of Mudfish? i really don't know at the moment but a fix or something i could do to stop this would greatly be appreciated thanks for you'r reply! hope to hear from someone soon again!
