After installing version 3.7.2 of Ky_Trail plug-in for 3ds Max 2009 (64-bit) during initializing of the plug-in for some users has been displaying the error message (Error Code: 14001). This error arose as a consequence of incompatibility of some updates to the compiler (Microsoft Visual C++ 2005) with 3ds Max 2009.
Plug-in Ky_Trail for 3ds Max 2009 (32-bit and 64-bit) has been recompiled. To the plug-in files was assigned a version number 22.214.171.124.
I thank all users reported problems.
