No, don't buy Pro until you know basic's going to work.
You could download the latest basic release (4.12.6), or there's a 4.13.0 beta as well, & see if things improve. If you love the 4.12.3 Pro, make sure the installer's saved in case you want to revert back to it at any stage. If you do upgrade to a newer version, delete your prefs after installing it.
Are you using SP2 & if so, are you using any of the connections patches?
Can you have a look on your router or modem & find out the brand & model? Or aren't you connecting through any device? |
