[vpn-help] win7 x64 bugcheck crashes - vpn-client-2.1.5-release

[William Baum]

Update:

For those having issue with BSOD's, especially win7 x64 
IRQL_NOT_LESS_OR_EQUAL in vfilter.sys ( vfilter+29a6 ) (2.1.5-release)

2.1.6-beta-3 seems to have solved this issue for me.  2.1.5 was bsod'ing 
every day or two, and 2.1.6-beta-3 has been going strong for 4 days with 
no issues whatsoever. 

So while I spose it's still too early to declare the issue resolved, it 
looks good so far.
